Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to an electromagnetic amplitude and phase regulation board, method, and storage medium. Background Art

[0002] Metasurface is a periodic planar array composed of artificial meta-atoms, corresponding to two-dimensional metamaterials, with advantages such as low loss and easy fabrication. Due to its excellent performance in regulating the amplitude, phase, polarization, etc. of electromagnetic waves, it has received extensive attention.

[0003] In recent years, the research focus has gradually shifted from passive metasurfaces with fixed functions to active metasurfaces with adjustable characteristics. The active switching mechanisms of subwavelength optical modes include mechanical deformation, free carrier density modulation, electro-optic effect in liquid crystals, and phase transition. Information metasurfaces with multiple functions are promising in applications such as electromagnetic signal coverage, wireless communication, optical imaging, and sensing.

[0004] Current information metasurfaces are usually realized by integrating diodes into meta-atom units. Programmable metasurfaces can increase the communication capacity in channels, which is considered a key technology for next-generation communication. So far, these dynamically controllable metasurfaces require continuous power supply to maintain the electromagnetic characteristics of each meta-atom. In large array application scenarios, this unstable modulation poses a huge challenge to the feeding network and power consumption. Mechanically reconfigurable metasurfaces can be non-volatile and low-power, but still lack efficient deformation and regulation mechanisms. Secondly, geometric phase utilizes the sudden change of phase brought by in-plane geometric rotation of meta-atoms, which can be well explained by the Poincaré sphere and Jones matrix, and has the advantage of being frequency-independent, and has been widely used in fields such as orbital angular momentum, superlens, holographic imaging, and nonlinearity. Its defect is that it can only be used for circular polarization regulation, and the placement angle of each meta-atom in the plane needs to be set in advance, making it difficult to achieve reconfigurability.

[0049] The following description and the accompanying drawings fully disclose specific embodiments of the present application, enabling those skilled in the art to practice them.

[0050] It should be clear that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0052] In the description of the present application, it should be understood that terms such as "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. In addition, in the description of the present application, unless otherwise specified, "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0053] The present application provides an electromagnetic amplitude and phase regulation board, method, and storage medium to solve the problems existing in the above related technical problems. In the technical solution provided by the present application, since the present application combines a meta-atom array module with a remote control module, the regulation of electromagnetic amplitude and phase can be achieved through the remote control module. The following uses exemplary embodiments for detailed description.

[0054] Please refer to Figure 1 , which shows a schematic structural diagram of an electromagnetic amplitude and phase regulation board provided by an exemplary embodiment of the present application.

[0055] As Figure 1 shown, the electromagnetic amplitude and phase regulation board provided by the embodiment of the present application includes: a meta-atom array module, a remote control module, and a mechanical rotation drive module; wherein, the meta-atom array module is mechanically connected to the mechanical rotation drive module, and the mechanical rotation drive module is electrically connected to the remote control module; wherein, the remote control module is configured to receive control parameters sent from a client and send them to the mechanical rotation drive module; the mechanical rotation drive module is configured to control the array rotation angle of the meta-atom array module and the incident angle of electromagnetic waves according to the received control parameters to achieve the regulation of electromagnetic amplitude and phase.

[0056] In the embodiments of the present application, for example Figure 2 As shown, the meta-atom array module includes a first bracket, a second bracket, and a plurality of resonant units; wherein, one end of the plurality of resonant units vertically penetrates the horizontal plane of the first bracket at equal distances, and the other end of the plurality of resonant units vertically penetrates the horizontal plane of the second bracket at equal distances, and the plurality of resonant units are parallel to each other; wherein, any one end of the plurality of resonant units is mechanically connected to the mechanical rotation drive module.

[0057] Specifically, the microstructure of each resonant unit includes a dielectric substrate and a plurality of upper metal copper-clad layers; wherein, the plurality of upper metal copper-clad layers cover the dielectric substrate. Due to the non-local effect of the electric susceptibility, adjusting the incident angle and the rotation angle will change the electric susceptibility of the metasurface, resulting in symmetric transmission amplitude modulation and asymmetric phase modulation.

[0058] Furthermore, the microstructure has sub-wavelength dimensions, its thickness is only a few hundredths of the working wavelength, and it can be equivalent to an electric dipole. According to the non-local effect of the electric susceptibility, by controlling the array rotation angle and the incident angle of the electromagnetic wave, symmetric amplitude and asymmetric phase control of the transmission coefficient can be achieved. By combining adjacent arrays to rotate together, for electromagnetic waves incident at 45 degrees, normal reflection can be achieved, converted into backscattering, and then converted into the regulation of backscattering.

[0059] Furthermore, in terms of the processing technology, the microstructure is a two-dimensional surface structure and can be processed conveniently by using existing mature PCB processing technologies.

[0060] Specifically, each upper metal copper-clad layer has an S-shaped centrosymmetric structure; wherein, the thickness of each upper metal copper-clad layer is 0.035 mm; wherein, the dielectric material of the dielectric substrate is a polytetrafluoroethylene glass cloth copper-clad laminate.

[0061] Specifically, for example Figure 3 As shown, the S-shaped centrosymmetric structure has specific dimension parameters: the thickness of the copper-clad layer is 0.035 mm, m = 7 mm, n = 0.5 mm. The size of this unit structure can determine the operating frequency of the metasurface, that is, the resonant frequency of the equivalent electric dipole. The period distance p = 20 mm, l = 17.3 mm, and metasurfaces with different numbers of bits can achieve integer multiple expansion of the period distance. For example, the period of a 2-bit metasurface is 2p = 20 mm. The dielectric material of the dielectric substrate 1 is a polytetrafluoroethylene glass cloth copper-clad laminate F4BM, with a dielectric constant of 2.2, a loss tangent angle of 0.001, a substrate thickness h = 2 mm, a width w = 5 mm, and the length of each board surface is 400 mm and the width is 5 mm.

[0062] Furthermore, when it is in the S shape, it can be seen from the multipole expansion algorithm that the electric dipole component is much higher than other components, so it can be equivalent to an electric dipole. Compared with the existing common active metasurfaces integrating PIN diodes, varactor diodes, etc., this resonant unit does not require power supply to maintain its performance.

[0063] In an embodiment of the present application, for example Figure 2 As shown, the remote control module is a Bluetooth module; wherein, the Bluetooth module is communicatively connected to the client; wherein, the Bluetooth module is used to establish communication with the client, receive the control parameters sent from the client, and send them to the mechanical rotation drive module. The remote control method introducing the Bluetooth module is convenient and fast, and it is easier to accurately switch the rotation angle.

[0064] Specifically, the Bluetooth module communicates with the mobile APP developed on the client. The mobile APP side issues instructions such as rotation angle, rotation speed, rotation mode, etc., and can also receive the signals fed back by the control end to monitor its working state.

[0065] In an embodiment of the present application, for example Figure 2 As shown, the mechanical rotation drive module includes a servo and a microcontroller; wherein, the microcontroller is electrically connected to the servo, and the servo is mechanically connected to any one end of multiple resonant units to control the mechanical coaxial rotation of the multiple resonant units on the first bracket and the second bracket; wherein, the Bluetooth module is arranged on the microcontroller, and the microcontroller is electrically connected to the Bluetooth module.

[0066] Specifically, the microcontroller includes a PCA9685 driver and an open source electronic prototyping platform; wherein, the PCA9685 driver is electrically connected to the open source electronic prototyping platform; wherein, the PCA9685 driver is electrically connected to the servo, and the open source electronic prototyping platform is electrically connected to the Bluetooth module.

[0067] In a possible implementation manner, the open source electronic prototyping platform receives the control parameters sent from the Bluetooth module, processes the control parameters and then sends them to the PCA9685 driver; the PCA9685 driver generates 16-channel pulse width modulation signals according to the received data and sends them to the servo; the servo controls the rotation angle of the array of multiple resonant units and the incident angle of the electromagnetic wave according to the received 16-channel pulse width modulation signals.

[0068] Further preferably, the mechanical rotation drive part is an SG90 servo, a 16-channel Pulse Width Modulation (PWM) output module PCA9685 driver, and an open-source electronic prototyping platform Arduino, which can achieve precise control of the coaxial rotation angle of the array. The working voltage is 5V. Even when powered off, the array can maintain the existing rotation angle state and maintain the electromagnetic wave regulation function. At the same time, coaxial rotation can greatly reduce the complexity of the feeding network.

[0069] It should be noted that by adopting various different array combination rotation methods, or integrating the mechanism of geometric phase, or introducing the concept of mechanical coaxial rotation into microelectromechanical systems, reconfigurable microwave devices with more functions can be realized. Since the mechanical rotation method is adopted, it is not necessary to continuously supply power to each meta-atom to maintain the working state, reducing the complexity of the feeding network. Even after the device is powered off, it can continue to maintain the original function, that is, non-volatile (non-volatile is originally a term in the computer field. Non-volatile memory refers to a computer memory in which the stored data does not disappear when the current is turned off).

[0070] In the embodiment of the present application, first, when the client receives a control instruction, it generates control parameters and sends them to the remote control module. Then, the remote control module receives the control parameters sent from the client and sends them to the mechanical rotation drive module. Finally, the mechanical rotation drive module controls the array rotation angle of the meta-atom array module and the incident angle of the electromagnetic wave according to the received control parameters to achieve the regulation of electromagnetic amplitude and phase. Since the present application combines the meta-atom array module with the remote control module, the regulation of electromagnetic amplitude and phase can be achieved through the remote control module.

[0071] Next, the method for regulating electromagnetic amplitude and phase provided in the embodiment of the present application will be introduced in detail in combination with the attached Figure 4 - attached Figure 8 drawings.

[0072] Please refer to Figure 4 which is a schematic flowchart of a method for regulating electromagnetic amplitude and phase provided in the embodiment of the present application. As Figure 4 shown, the method of the embodiment of the present application may include the following steps:

[0073] S101, when the client receives a control instruction, generate control parameters and send them to the remote control module;

[0074] S102, the remote control module receives the control parameters sent from the client and sends them to the mechanical rotation drive module;

[0075] S103. The mechanical rotation drive module controls the array rotation angle of the meta-atom array module and the incident angle of the electromagnetic wave according to the received control parameters to achieve the regulation of the electromagnetic amplitude and phase.

[0076] In the embodiment of the present application, each meta-atom array rotates by the same angle simultaneously, which is called a 1-bit electromagnetic amplitude and phase regulation plate; every two arrays rotate symmetrically by the same angle to form a period, which is called a 2-bit electromagnetic amplitude and phase regulation plate. Further, 3-bit and 4-bit electromagnetic amplitude and phase regulation plates can be set. Due to the continuously adjustable change of the rotation angle of the servo motor, the system can achieve more functions.

[0077] Figure 5 It is the simulation result of the transmission amplitude when the incident angle θi = 45°, and the rotation angles θR = 45° and θR = -45° for the 1-bit electromagnetic amplitude and phase regulation plate. Both curves are close to 0 dB, with full transmission. The system has symmetric transmission amplitude regulation ability.

[0078] Figure 6 It is the simulation result of the transmission phase when the incident angle θi = 45°, and the rotation angles θR = 45° and θR = -45° for the 1-bit electromagnetic amplitude and phase regulation plate. When θR = 45°, the curve is almost constantly equal to 0 because the structure is perpendicular to the direction of the incident electric field and fails to excite the electric dipole response. When θR = -45°, the resonant structure is parallel to the direction of the incident electric field, and a phase coverage ability of 2π can be achieved. The system has asymmetric transmission phase regulation ability.

[0079] In this system, when obliquely incident, for symmetric rotation angles, the 1-bit metasurface system has symmetric amplitude regulation ability and phase regulation ability, which is caused by the non-local effect of the polarizability.

[0080] Figure 7 It is the simulation result of the reflection amplitude and the backscattering amplitude when the incident angle θi = 45°, and the rotation angles θR = 0° (the resonant structures are laid flat), 45°, 90° (the resonant structures are erected) for the 2-bit electromagnetic amplitude and phase regulation plate. It can be seen that when the rotating resonant structures change from being laid flat to being erected, the system changes from reflection to backscattering and then to reflection. The system has the ability to regulate high-order diffraction components.

[0081] Figure 8 It is for the 2-bit electromagnetic amplitude and phase regulation plate. Figure 7The corresponding far-field scattering simulation results can better show the beam scanning ability. When the incident angle θi = 45°, the reflection component is mainly concentrated in the 45° direction. The backscattering is mainly concentrated in the -40° direction. The deflection angle corresponding to the specific diffraction order can be obtained from the generalized Snell's law, where k0 is the wave number in free space, is the reflection angle or transmission angle, θi is the incident angle, m is the diffraction order, p is the period of the array, and λ is the corresponding operating wavelength.

[0082] It should be noted that in order to make up for the existing deficiencies and defects of the programmable metasurface, the present invention provides a Bluetooth remote-controlled mechanically reconfigurable electromagnetic amplitude and phase regulation board, which has the advantages of low loss, strong amplitude and phase regulation ability for microwave signals, can achieve specific high-order diffraction modes such as backscattering, can be remotely controlled and field programmable, and has diverse functions.

[0083] In the embodiment of the present application, first, when the client receives a control instruction, it generates control parameters and sends them to the remote control module. Then, the remote control module receives the control parameters sent from the client and sends them to the mechanical rotation drive module. Finally, the mechanical rotation drive module controls the array rotation angle of the meta-atom array module and the incident angle of the electromagnetic wave according to the received control parameters to achieve the regulation of electromagnetic amplitude and phase. Since the present application combines the meta-atom array module with the remote control module, the regulation of electromagnetic amplitude and phase can be achieved through the remote control module.

[0084] Those of ordinary skill in the art can understand that all or part of the processes of implementing the methods in the above embodiments can be completed by instructing relevant hardware through a computer program. The program can be stored in a computer-readable storage medium. When the program is executed, it can include the processes of the above method embodiments. Among them, the storage medium can be a magnetic disk, an optical disk, a read-only memory, or a random access memory, etc.

[0085] The above-disclosed are only the preferred embodiments of the present application. Of course, the scope of the rights of the present application cannot be limited by this.
