Description

Technical Field

[0001] The present invention relates to the technical field of high-frequency gravitational wave detection in the microwave band, and in particular to a microwave-band high-frequency gravitational wave detection device and detection method. Background Art

[0002] Detecting high-frequency gravitational waves is of profound importance and significance for cosmology and high-energy astrophysics. The gravitational wave frequency band is extremely broad, corresponding to information on different formation mechanisms and sources. However, gravitational wave detectors are limited by their detection principles, instrument properties, and noise perturbations, resulting in strict constraints on the frequency bands within which they target gravitational wave signals. Currently, there are three main types of gravitational wave detectors, categorized by their detection frequency bands: very low frequency (VLF), medium frequency (MF), and high frequency.

[0003] Traditional gravitational wave detection devices use laser interferometers to detect gravitational waves. Essentially, they are length-measuring tools that use the wavelength of a laser as a known length and measure displacement via a Michelson interferometer system. The operating principle of traditional gravitational wave detection devices is based on Einstein's general theory of relativity, which predicts that gravitational waves, as ripples in spacetime, can travel through the universe at the speed of light, causing extremely small changes in the length of objects in their path. The laser interferometer in the detector typically consists of two long, mutually perpendicular arms, each several kilometers long, with a vacuum inside to reduce external interference. Laser light originates from a central light source and is split into two beams by a beam splitter. These beams travel along and reflect from the two perpendicular arms, ultimately reuniting at the detector. Under normal circumstances, the two beams have the same stable path length, and the interference pattern appears as a stable alternating pattern of light and dark fringes. However, when a gravitational wave passes, it extremely slightly changes the length difference between the two arms (usually only on the order of a proton diameter or less), causing a change in the optical path difference between the two laser beams and a phase shift in the interference pattern. This change is the gravitational wave signal.

[0004] Technical details of this type of gravitational wave detector include using a Fabry-Perot cavity to increase the number of round trips of light within the arms, thereby amplifying the gravitational wave effect; utilizing techniques such as quantum squeezing to reduce quantum noise levels and improve the signal-to-noise ratio; and employing complex suspension systems and active control techniques to mitigate the effects of environmental noise such as earthquakes and acoustic waves. These techniques enhance the instrument's measurement sensitivity, enabling the detection of extremely weak gravitational wave signals. However, existing ground-based laser interferometer gravitational wave detectors are severely affected by ground-based noise disturbances, limiting their detection frequency range to tens to hundreds of hertz. Their primary target is typically mid-frequency gravitational waves from the merger of two compact objects. This type of device has significant detection limitations for gravitational wave signals that carry important cosmological information, such as quantum fluctuations in the very early universe, the interaction between astrophysical plasmas and electromagnetic fields, cosmic strings, large extra dimensions of space, primordial gravitational waves, and primordial black holes.

[0005] In recent years, the use of pulsar timing arrays to observe very low-frequency gravitational wave effects has become a research hotspot. However, existing mainstream international methods for detecting high-frequency gravitational waves still face numerous challenges. For example, the sensitivity of the devices is significantly different from the amplitude of the gravitational wave signals, making successful high-frequency gravitational wave detection difficult under current technical conditions.

[0031] Reference Figure 1 An embodiment of the present invention provides a microwave-band high-frequency gravitational wave detection device, comprising a first input module, a coupling module, and a detection module, wherein the detection module comprises a detector and a signal analysis module, wherein:

[0032] The output end of the coupling module is communicatively connected to the input end of the detector, and the detector is used to receive the transverse perturbation photon flow output by the coupling module. The output end of the detector is communicatively connected to the input end of the signal analysis module. Specifically, the coupling module is used to provide a static magnetic field. When gravitational waves exist in space, the gravitational waves and the static magnetic field can interact to generate a perturbed electromagnetic field. In a preferred implementation of this embodiment, a static magnetic field is provided in a direction perpendicular to the propagation direction of the microwave electromagnetic beam, because the perturbed electromagnetic field generated is maximum when the propagation direction of the microwave electromagnetic beam is perpendicular to the direction of the static magnetic field. The microwave electromagnetic beam is used to amplify the transverse energy flow of the perturbed electromagnetic field to generate a transverse perturbation photon flow. The microwave electromagnetic beam is perpendicular to the direction of the transverse perturbation photon flow. The detector is used to detect the transverse perturbation photon flow. When a transverse perturbation photon flow signal is detected, the transverse perturbation photon flow signal is sent to the signal analysis module. The signal analysis module is used to analyze the transverse perturbation photon flow to determine the physical characteristics of the transverse perturbation electric field, and determine the physical parameters of the high-frequency gravitational waves based on the physical characteristics, thereby obtaining the detection results of the high-frequency gravitational waves. The physical parameters of high-frequency gravitational waves include frequency and amplitude.

[0033] Specifically, the coupling module includes a superconducting magnet that can generate a static magnetic field. The static magnetic field is designed with a cavity structure. When the angle between the static magnetic field inside the cavity and the propagation direction of the gravitational wave is non-zero, a disturbed electromagnetic field can be generated. The propagation direction of the microwave electromagnetic beam is perpendicular to the direction of the static magnetic field. Since the gravitational wave signal exists in the entire space, there is no need to input the gravitational wave separately. In this embodiment, the operating frequency range of the microwave electromagnetic beam generator is 10 9 Hz to 10 12 Hz. The microwave electromagnetic beam utilizes a corrugated feed horn. In this embodiment, the propagation direction of the microwave electromagnetic beam is perpendicular to the subsequently generated transverse perturbation electric field. A static magnetic field is distributed within the cavity, and the directions of the static magnetic field, microwave electromagnetic beam propagation, and transverse perturbation photon flux are perpendicular to each other.

[0034] In a preferred embodiment of this embodiment, the cavity inside the disturbing electromagnetic field generating container is vacuum, so as to reduce the interference of the external environment on the experimental results and improve the detection accuracy. Figure 1 In this embodiment, the disturbance electromagnetic field generating container adopts a vacuum tube, and the shape of the cavity is cylindrical; both ends of the vacuum tube are covered with end walls, so that a vacuum cavity is formed inside the disturbance electromagnetic field generating container; the signal output end of the first input module is arranged at the end wall of one end of the disturbance electromagnetic field generating container (vacuum tube), and the detector is arranged at the end wall of the other end of the disturbance electromagnetic field generating container (vacuum tube); the propagation direction of the gravitational wave is parallel to the central axis direction of the vacuum tube.

[0035] The inner wall of the cavity is provided with a temperature sensor for collecting the temperature inside the cavity. The temperature sensor can monitor the temperature changes in the cavity in real time and provide a reference basis for subsequent data analysis.

[0036] The output end of the temperature sensor is communicatively connected to a temperature regulating component, which can regulate the temperature inside the cavity. The user adjusts the temperature inside the cavity by controlling the temperature regulating component, and uses the temperature sensor to monitor the temperature inside the cavity in real time, so that the user can detect the temperature environment inside the container generating the disturbed electromagnetic field, thereby facilitating the user to measure the changes in the transverse mode behavior of monochromatic light at different temperatures, verify the influence of thermal noise, and improve the accuracy of the thermal noise influence verification results.

[0037] In this embodiment, the static magnetic field is a strong magnetic field with an intensity of 5 to 10 T, and a spatial scale of the static magnetic field on the order of meters. Specifically, a superconducting magnet can be used to generate a static magnetic field of this intensity, and the stability of the magnetic field can be maintained by a precise magnetic field control system.

[0038] The microwave electromagnetic beam propagates perpendicularly to the transverse perturbed photon stream. It amplifies the transverse energy flow of the perturbed electromagnetic field, generating a transverse perturbed photon stream. In this embodiment, the microwave electromagnetic beam uses a quasi-Gaussian beam generated by a corrugated feed horn. This beam effectively provides a longitudinal magnetic field, which improves detection accuracy.

[0039] Reference Figure 2 , the static magnetic field is recorded as Static magnetic field The interaction with high-frequency gravitational waves (HFGWs) generates a disturbed electromagnetic field, where the electric field portion corresponding to the transverse energy flow of the disturbed electromagnetic field is recorded as The longitudinal magnetic field provided by the microwave electromagnetic beam is expressed as Microwave electromagnetic beam and transverse disturbance electric field Coupling to form a transverse perturbation photon flow signal

[0040] The detector is used to detect the transverse perturbation photon flow. When a transverse perturbation photon flow signal is detected, the transverse perturbation photon flow signal is sent to the signal analysis module. The detector can be a highly sensitive photon detector capable of capturing weak photon flow signals.

[0041] The signal analysis module analyzes the transverse perturbation photon flux to determine the physical characteristics of the transverse perturbation electric field, and based on these characteristics, determines the detection results of high-frequency gravitational waves. The signal analysis module includes a signal processing unit and a data analysis unit. The signal processing unit filters and amplifies the received signal, while the data analysis unit extracts the physical characteristics of the transverse perturbation electric field, such as intensity, direction, and frequency, from the processed signal to determine the presence of high-frequency gravitational waves.

[0042] According to the existing technology, a microwave source with strong power can be selected as much as possible to Amplification is achieved to form a transverse disturbance photon flow signal that can be detected

[0043] When selecting the microwave electromagnetic wave source, the quasi-Gaussian beam generated by the corrugated feed horn is preferred (such as Figure 3 The main role of the quasi-Gaussian beam in this project is to provide a longitudinal fluctuating magnetic field. With the transverse disturbance field Coupling to form a transverse perturbation photon flow signal Transverse perturbation photon flow signal The physical characteristics are: it is the maximum value at the light waist, although as the propagation distance increases, Attenuation, but it is faster than the Gaussian beam itself It is much slower, which plays an important role in improving the signal-to-noise ratio; where w represents the sound power and r represents the distance from the sound source. This physical property, the transverse perturbation photon flow signal Background noise Filter out. Background noise of this solution It can be divided into intrinsic noise and extrinsic noise. Intrinsic noise is the noise source caused by the light source itself and optical components, mainly including shot noise, radiation pressure noise, and diffraction noise; external noise refers to noise from the environment or external interference sources, mainly including thermal noise, magnetic field inhomogeneity, and scattering noise.

[0044] The transverse perturbation photon flow signal and background noise in the present invention have very different physical behaviors, including different spatial attenuation rates, intensity distributions, propagation directions and wave impedances, which enables the system to have a good signal-to-noise ratio and effectively distinguish effective signals from background noise.

[0045] Since the amplitude of high-frequency gravitational waves is usually very weak (the typical value of the dimensionless amplitude of high-frequency gravitational waves is 10 -30 ), the resulting transverse disturbance electric field It must be very weak, and the corresponding transverse perturbation photon flow signal ( Figure 1 in ) is proportional to The intensity of the transverse perturbation photon flux will also be extremely weak. Therefore, in a preferred embodiment of this embodiment, the microwave-band high-frequency gravitational wave detection device also includes an amplifier. The amplifier's input terminal is communicatively connected to the output terminal of the coupling module, and the amplifier's output terminal is communicatively connected to the detector's signal input terminal. The amplifier is used to amplify the transverse perturbation photon flux signal, increasing its strength and facilitating detection by the detector.

[0046] During the system initialization phase, the microwave-band high-frequency gravitational wave detection device needs to be calibrated. Specific steps include: generating a static background magnetic field at the front end and controlling its strength; introducing a microwave electromagnetic beam to couple it with the perturbed electromagnetic field; detecting the transverse non-zero photon flux at the rear end, debugging the system, and recording its operating parameters; and observing the perturbed transverse photon flux to verify the validity of the theoretical mechanism in the presence of gravitational waves coupled to the static magnetic field.

[0047] In order to verify the effectiveness of the system, signal simulation tests can also be carried out: artificially simulate a non-zero transverse perturbation electromagnetic field to couple it with the electromagnetic beam; observe the transverse perturbation photon flow at the end part to test the predictiveness of the theoretical mechanism and preliminarily build an experimental platform.

[0048] In practical applications, the working principle of the microwave-band high-frequency gravitational wave detection device of this embodiment is as follows:

[0049] First, in the coupling module, gravitational waves couple with the static magnetic field to generate a perturbed electromagnetic field. The microwave electromagnetic beam in the first input module interacts with the perturbed electromagnetic field, amplifying the transverse energy flow of the perturbed electromagnetic field into a transverse perturbed photon flow.

[0050] The transverse perturbation photon flow is further amplified by the amplifier and then captured by the detector; the detector sends the captured signal to the signal analysis module.

[0051] The signal analysis module processes and analyzes the received signals, extracts the physical characteristics of the transverse disturbance electric field, such as intensity, direction, and frequency, and based on this, determines whether high-frequency gravitational waves exist and obtains the detection results.

[0052] Reference Figure 4 Based on the same inventive concept, an embodiment of the present invention provides a high-frequency gravitational wave detection method. The high-frequency gravitational wave detection method includes the following steps:

[0053] S1. Determine the disturbed electromagnetic field generated by the coupling of static magnetic field and gravitational waves based on Maxwell's equations in curved spacetime.

[0054] In the context of curved spacetime, the process of the coupling of static magnetic fields and gravitational waves to produce transverse energy flow in the perturbed electromagnetic field can be summarized as follows: first, the Maxwell equations for curved spacetime are established based on general relativity, and gravitational waves are regarded as small perturbations of the metric tensor; then the electromagnetic field is decomposed into a static background magnetic field and a perturbation field, and the modulation effect of gravitational waves on the background magnetic field (static magnetic field) is analyzed through linearized equations; finally, the coupling term is solved to obtain the transversely propagating perturbation electromagnetic field.

[0055] In this embodiment, since the gravitational waves we detect are already diffuse in space, there is no need to obtain them separately. The strength of the static magnetic field is 5T to 10T, and the spatial scale of the static magnetic field is on the order of meters. The direction of the static magnetic field is perpendicular to the propagation direction of the gravitational waves to be detected, which can maximize the interaction effect between the gravitational waves and the static magnetic field. Please refer to the process of the transverse perturbation electric field generated by the static magnetic field and the gravitational waves. Figure 2 .

[0056] S2. Amplify the transverse energy flow of the disturbed electromagnetic field into a transverse disturbed photon flow through a microwave electromagnetic beam, wherein the microwave electromagnetic beam is arranged perpendicular to the direction of the transverse disturbed photon flow.

[0057] In this embodiment, the microwave electromagnetic beam is a quasi-Gaussian beam generated by a corrugated feed horn, with a frequency range of 10 9 Hz to 10 12 Hz. The propagation direction of the microwave electromagnetic wave beam is perpendicular to the direction of the transverse disturbance photon flow.

[0058] S3. Analyze the transverse perturbation photon flow and obtain the physical characteristics of the transverse perturbation electric field.

[0059] The physical characteristics of the disturbed electromagnetic field include at least one of the intensity, direction, and frequency of the transverse disturbed electric field. By analyzing these physical characteristics, the properties of the gravitational waves can be inferred, thereby determining the presence of high-frequency gravitational waves.

[0060] S4. Determine whether high-frequency gravitational waves exist based on the physical characteristics of the transverse disturbance photon flow and obtain high-frequency gravitational wave detection results.

[0061] Specifically, through the transverse perturbation photon flow signal, the physical characteristics such as the transverse perturbation field intensity, direction and frequency are inferred, and the high-frequency gravitational wave related characteristics are further given.

[0062] In a preferred implementation of this embodiment, the frequency gravitational wave detection method further includes:

[0063] S5. Detecting the transverse non-zero photon flow output by the transverse photon flow generation module, analyzing the transverse non-zero photon flow to obtain an analytical result, and adjusting the direction and intensity of the static magnetic field according to the analytical result.

[0064] By adjusting the direction and intensity of the static magnetic field and the direction of the microwave electromagnetic beam based on the analytical results, the possibility of inaccurate high-frequency gravitational wave detection results due to misalignment of the static magnetic field or the microwave electromagnetic beam can be reduced.

[0065] In addition, in order to verify the reliability of the detection results, repeated measurements can be carried out and the results can be statistically analyzed. Based on the results of the statistical analysis, the parameters of the microwave high-frequency gravitational wave detection device can be adjusted to further improve the accuracy of the detection results.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
