Ultra-wideband high-power microwaves possess extremely fast rise times and a wide spectral range, covering various target response frequencies and causing damage to electronic systems. Narrowband high-power microwave sources mainly include devices such as relativistic klystrons, relativistic magnetrons, and gyrotrons; their research focuses on improving repetition rate and microwave pulse width. Currently, high-power microwave technology is widely used in communications, radar, medical applications, pest control, and food processing. In the military field, high-power microwave technology is used for electronic jamming, radio disruption, and missile interception. Besides these uses, there are many other applications: a common application is in non-destructive testing (NDT). High-power microwaves can generate very strong electromagnetic pulses, which can be used to detect internal defects and damage in metal structures. This NDT technology has wide applications in aerospace, automotive, and railway industries. Furthermore, high-power microwaves can also be used for energy transfer. By transmitting a high-power microwave beam to a receiver, electrical energy or other forms of energy can be transferred to the desired location. This technology can be used in wireless charging, space energy transfer, and other fields. In summary, high-power microwave technology has broad application prospects.

[0003] However, high-power microwave sources still have some drawbacks, such as large size, low efficiency, short lifespan, and difficult maintenance. Furthermore, the increasing destructive impact of the strong electromagnetic radiation from high-power microwaves on modern electronic devices necessitates the development of new high-power microwave sources to address this challenge.

[0004] Against this backdrop, this invention proposes a controllable microwave source and control method based on a laser accelerator. This technology utilizes the high-intensity, wide-bandwidth electromagnetic pulses generated during laser target firing as a seed source for high-power microwaves. Through laser target firing electromagnetic pulse radiation technology, antenna technology, and microwave technology, a novel implementation principle and scheme for a high-power microwave source are proposed, which can be used for applications such as generating high-power microwave weapons, wireless energy transmission, and non-destructive testing.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The purpose of this invention is to provide a controllable microwave source and control method based on a laser accelerator. By using a laser source to excite a radiation source to emit thermionic electrons and generate an electromagnetic pulse, which is then modulated and amplified by a magnetron and radiated directionally through a directional antenna, the invention solves the problems of large size and low efficiency of traditional high-power microwave sources and reduces the destructive impact on electronic equipment.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1 As shown, an embodiment of the present invention provides a controllable microwave source based on a laser accelerator, the microwave source comprising:

[0043] Laser source 1, radiation source 2, magnetron 3, and directional antenna 4.

[0044] The laser source 1, the radiation source 2, and the magnetizer 3 are arranged accordingly. The laser source 1 emits a laser to the radiation source 2 to excite the radiation source 2 to generate an electromagnetic pulse. The magnetizer 3 is used to collect the electromagnetic pulse and modulate and amplify the electromagnetic pulse to obtain a modulated and amplified electromagnetic pulse.

[0045] like Figure 2As shown, the radiation source 2 specifically includes: a target body 5, a target rod 6, a supercapacitor 11, and a radiating antenna 12; the target body 5 is disposed on the target rod 6, and the target body 5 is a capacitor target; the radiating antenna 12 is disposed on the surface of the target rod 5; the positive terminal of the supercapacitor 11 is electrically connected to the target body 5, and the negative terminal of the supercapacitor 11 is electrically connected to the target rod 6.

[0046] After being excited by the laser emitted by the laser source 1, the target 5 emits thermionic electrons. These electrons are replenished by the supercapacitor 11. The target rod 6 is a metal target rod and is grounded. The target rod 6 can act as a section of wire on the lower electrode plate 10 of the capacitor target. When thermionic electrons are emitted, they are quickly replenished from the supercapacitor 11 and the ground, forming a current on the target rod 6. Finally, the radiating antenna 12 is driven by the current to emit electromagnetic pulses. The base on which the radiating antenna 12 is mounted is located on the target 5, and the interior of the radiating antenna 12 has a hole for thermionic electron emission. The radiating antenna 12 is a multi-array antenna or a horn antenna, such as... Figure 3 As shown, multiple radiating antennas 12 can be configured to form a directional array antenna, such as... Figure 4 As shown, the radiating antenna 12 can also be connected to the target rod via a signal line.

[0047] A capacitor target can be viewed as a type of supercapacitor, with its two plates resembling tentacles that can extend to a certain distance.

[0048] When the laser emitted by the laser source 1 interacts with the capacitor target, the laser beam irradiates the surface of the capacitor target, causing plasma to form on the surface of the target material. This plasma contains a large number of free electrons. After the laser beam ends, these free electrons are subjected to the strong magnetic field on the surface of the target material, and are strongly accelerated and heated, eventually forming an electron beam, thereby generating an electromagnetic pulse.

[0049] Specifically, laser energy is converted into heat energy, generating hot electrons. These hot electrons are accelerated under the influence of the electric field of the capacitive target, and the electric field can also counteract the potential difference in the Debye layer, enhancing the escape ability of the hot electrons. Since the interaction between the laser and the capacitive target generates hot electrons, and these hot electrons generate EMP (electromagnetic pulse) radiation during their escape, controlling the total number of free electrons in the capacitive target can control the EMP radiation intensity as a means of controlling EMP radiation intensity. By adjusting the capacitance and voltage values ​​of the capacitive target, the number and position of free electrons can be controlled, thereby controlling the generation and escape of hot electrons. In addition, the number and energy of hot electrons generated in the target 5 can be controlled by controlling parameters such as laser power, wavelength, and pulse width, thereby achieving more precise EMP control.

[0050] Traditional electromagnetic pulse (EMP) weapons use capacitors to store electrical energy and discharge it through vacuum tubes to generate powerful electromagnetic pulses. However, this method requires a large number of vacuum tubes and capacitors, resulting in a large size and weight for the weapon system. Laser-based EMP weapon systems, on the other hand, utilize laser-generated EMPs from laser targets as a microwave source, avoiding the need for numerous capacitors and vacuum tubes, thus achieving a lighter and smaller weapon system. Furthermore, the electromagnetic pulses generated by laser targets have a very wide frequency band, which can be directly converted into high-power microwave weapons, opening up a wider range of applications.

[0051] The capacitor target specifically includes: an upper electrode plate 8, a lower electrode plate 10, an intermediate dielectric layer 9, and a supercapacitor 11. The upper electrode plate 8, the intermediate dielectric layer 9, and the lower electrode plate 10 are arranged sequentially from top to bottom. The upper electrode plate 8 is connected to the positive terminal of the supercapacitor 11, and the lower electrode plate 10 is disposed on the target rod 6. Emission holes are provided on the upper electrode plate 8 and the intermediate dielectric layer 9. The upper electrode plate 8 is electrically connected to the positive terminal of the supercapacitor 11, and the lower electrode plate 10 is connected to the negative terminal of the supercapacitor 11. Thermionic electrons can escape through the emission holes, and the amount of positive and negative charge between the electrodes of the capacitor target can be controlled by controlling the charge level of the supercapacitor 11.

[0052] The intermediate dielectric layer 9 includes, but is not limited to, air or polytetrafluoroethylene (PTFE). Using different materials in the intermediate dielectric layer 9 of the capacitor target can adjust the capacitance value of the capacitor target. Using a material with a higher relative permittivity results in a higher capacitance value, and vice versa. This is because the dielectric constant is related to the degree of polarization of the material. When the degree of polarization is high, the electric field can accumulate more charge in the dielectric, thereby increasing the capacitance value. Furthermore, the capacitance value of the capacitor target is related to the number of charges it carries; as the capacitance value increases, the number of charges carried by the capacitor target also increases, and vice versa. Therefore, by adjusting the capacitance value, precise control of the number of free electrons on the negative electrode of the capacitor target can be achieved.

[0053] There is a specific relationship between the electric field strength in the capacitor target and the position of the charge distribution on the capacitor target. The supercapacitor 11 has a controllable charge and voltage and can withstand strong current. According to the capacitance formula, C = Q / U, where C is capacitance, Q is charge, and U is voltage, when the charge of the supercapacitor 11 remains constant, increasing the voltage of the capacitor target will increase the electric field strength between the two plates. According to the electric field strength formula, E = V / C, where E is electric field strength, V is voltage, and C is capacitance, this will cause the positive and negative charges on the capacitor target to be closer to the surface of the target body 5; conversely, if the voltage of the capacitor target is decreased, the electric field strength decreases, and the positive and negative charge distribution will be closer to the center position between the two plates. Therefore, by controlling the voltage of the supercapacitor 11, the position of the charge distribution on the capacitor target can be controlled.

[0054] The supercapacitor is a high-energy-density electronic energy storage device, characterized by fast charging speed, high discharging rate, and long cycle life. Laser-type electromagnetic pulse weapon systems utilize supercapacitors as an electronic energy replenishment source, which can significantly increase the weapon system's electrical energy output, thereby enhancing its strike capability.

[0055] A filter 7 is provided on the target rod 6, and the target rod 6 is grounded. It is used to filter electromagnetic pulses outside the preset frequency band, so that the target 5 emits electromagnetic waves in the preset frequency band.

[0056] The laser-type electromagnetic pulse weapon system uses a system consisting of the target body 5, the target rod 6, the supercapacitor 11, and the radiating antenna 12 as the radiation source 2. It can emit electromagnetic pulses in a preset frequency band. In addition, it can combine the modulation and amplification effect of the magnetron 3 and the directional antenna 4 to effectively focus microwave energy onto the target, thereby improving the weapon system's strike accuracy and lethality.

[0057] The magnetocontroller 3 specifically includes: a collecting antenna, a modulation circuit, and an amplification circuit.

[0058] The collecting antenna is electrically connected to the modulation circuit, and the collecting antenna is used to collect electromagnetic pulses and transmit the electromagnetic pulses to the modulation circuit; the modulation circuit is electrically connected to the amplification circuit, and the modulation circuit is used to modulate the electromagnetic pulses to obtain modulated electromagnetic pulses; the amplification circuit is electrically connected to the directional antenna 4, and the amplification circuit is used to amplify the modulated electromagnetic pulses to obtain modulated and amplified electromagnetic pulses, and transmit the modulated and amplified electromagnetic pulses to the directional antenna 4. Figure 3As shown, in contrast, without the modulation and amplification effect of the magnetron 3, the intensity and accuracy of the emitted electromagnetic pulse are not high. The magnetron 3 plays the role of collecting, modulating, and amplifying the electromagnetic pulse signal. The collecting antenna, modulation circuit, and amplification circuit in the magnetron 3 can realize the collection, modulation, and amplification of the electromagnetic pulse signal. The magnetron 3 outputs the electromagnetic pulse signal modulated as required through the signal feeder and connects it to the directional antenna 4. The radiation direction of the directional antenna 4 is aligned with the target position, thereby radiating the amplified electromagnetic pulse signal to the designated location. This makes the amplified electromagnetic pulse a narrowband high-power microwave signal, which is finally amplified and propagated to the corresponding location through the antenna. The advantage of this method is that it can achieve precise control of the electromagnetic pulse, and the frequency and power of the microwave signal can be adjusted to control the intensity of the electromagnetic pulse radiation. In addition, by using the magnetron 3 to regulate the microwave signal, it can be converted into a narrowband high-power microwave source, thereby increasing the power density of the microwave signal and enhancing the radiation effect of the electromagnetic pulse.

[0059] The directional antenna 4 is electrically connected to the magnetron 3. The directional antenna 4 is used to radiate the modulated and amplified electromagnetic pulse to a preset position. The radiating antenna 12 and the directional antenna 4 are multi-array antennas or horn antennas.

[0060] When good antenna directional performance is required, the overall structure can be designed as a type with good directivity, such as an array antenna or a horn antenna. Since the antenna has a certain transmission frequency band, fixed-frequency transmission can be achieved by selecting equivalent antennas of different frequency bands, i.e., controlling the overall structure, or by connecting a filter 7 in the target rod 6. The radiation intensity of EMP can also be indirectly controlled by controlling the material type of the target rod 6. For example, using copper, which has good conductivity, as the target rod 6 can radiate EMP more strongly. In order to concentrate the electromagnetic pulse in one direction, a multi-array directional antenna 4 can be used. The multi-array directional antenna 4 is composed of multiple small antennas, each of which can emit electromagnetic waves and control the radiation direction of the electromagnetic waves. These small antennas can be adjusted so that their radiation direction is concentrated in a specific direction, thereby generating highly directional electromagnetic pulse radiation.

[0061] The process by which the magnetocontroller 3 and the directional antenna 4 enhance electromagnetic pulse radiation is achieved by utilizing the principle of generating electromagnetic pulses mentioned above. A microwave signal is generated through an electromagnetic pulse source (radiation source 2), and then this microwave signal is input into the magnetocontroller 3, which then regulates the microwave signal.

[0062] This invention also provides a control method for a controllable microwave source based on a laser accelerator as described above, the control method comprising:

[0063] The voltage value of the supercapacitor 11 in the radiation source 2 is controlled to adjust the accumulation position of positive and negative charges in the capacitor target.

[0064] The capacitance value of the supercapacitor 11 in radiation source 2 is controlled to adjust the number of positive and negative charges on the target 5 in radiation source 2.

[0065] The frequency range of the control filter 7 is adjusted to control the radiation frequency of the electromagnetic pulse from the radiation source 2.

[0066] The power of the electromagnetic pulse is adjusted by controlling the modulation parameters and amplification factor of the magnetron 3.

[0067] The laser-based electromagnetic pulse weapon system employs a technology that uses multi-variable parameters as the microwave adjustment source. These parameters include: the voltage and capacitance of the supercapacitor 11, the power, wavelength, and pulse width of the incident laser, the frequency range of the filter 7, and the modulation parameters and amplification factor of the magnetron 3. This allows for precise control and adjustment of microwave energy, thereby improving the weapon system's accuracy and reliability. The laser-based electromagnetic pulse weapon system integrates the characteristics of traditional microwave systems, featuring long service life, high power, adjustable frequency, and diverse modulation methods to meet the needs of various applications. Simultaneously, it also boasts advantages such as high energy density, stable optical components, and fast response speed.
