[0023] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0024] The inventors have discovered that, at present, in the process of controlling the voltage of the metasurface structure, the voltage control signal of each surface unit of the metasurface structure can be calculated first, and each surface unit can be grouped according to the voltage control signal, and then one group is selected from multiple groups, and a scan signal is sent to the scan line driving circuit to select each surface unit of the group, and then the voltage control signal of the group is sent to the signal line driving circuit, and loaded to each surface unit after digital-to-analog conversion, until the voltage control signal is loaded to each surface unit of each group.

[0025] This embodiment provides a solution that can solve the above-mentioned problem. The specific implementation methods of this application are described in detail below in conjunction with the accompanying drawings.

[0026] Please refer to Figure 1 , Figure 1 A schematic flow chart of a control method for a super-surface structure provided by the present embodiment is exemplified. The control method for a super-surface structure may include the following steps.

[0027] Step S110 , providing a control interface 100 , wherein the control interface 100 includes a parameter setting area 110 .

[0028] In this embodiment, please refer to Figure 2 , Figure 2The schematic diagram of the control interface 100 provided in the example embodiment may include the parameter setting area 110, and the parameter setting area 110 may be used to set the incident angle (e.g., inci_AZ, inci_EL), the exit angle (e.g., radi_AZ, radi_EL) and the number of voltage channels of a surface unit, etc.

[0029] Step S120, in response to a user operation, obtaining a first parameter input by the user in the parameter setting area 110, wherein the first parameter includes an incident angle and an exit angle of the metasurface structure.

[0030] In this embodiment, the parameters such as the incident angle, the exit angle and the number of voltage channels of the metasurface structure input by the user in the parameter setting area 110 can be obtained, and the first parameter input by the user in the parameter setting area 110 can be saved as a configuration file.

[0031] In addition, the client may also obtain the first parameter from a saved configuration file, so that the user is prevented from manually inputting the first parameter, which is beneficial to improving efficiency.

[0032] Step S130: generating a control signal according to the first parameter, wherein the control signal includes voltage data corresponding to each voltage channel of the metasurface structure.

[0033] In this embodiment, the control signal corresponding to the first parameter can be generated according to the first parameter obtained in step S120, and the control signal may include the voltage data corresponding to each voltage channel of the metasurface structure, wherein the voltage data corresponds to the voltage channel one by one.

[0034] Step S140: sending the control signal to the metasurface structure, so that the metasurface structure adjusts the voltage data corresponding to each voltage channel of the metasurface structure according to the control signal.

[0035] In this embodiment, the control signal obtained in step S130 can be sent to the metasurface structure, so that the metasurface structure sequentially adjusts the voltage values ​​of the voltage channels of the metasurface structure according to the order of the voltage data in the control signal.

[0036] In the above design, the user inputs the first parameter in the parameter setting area 110 to directly generate the control signal, and sends the control signal to the metasurface structure, so that the metasurface structure adjusts the voltage values ​​corresponding to each of the voltage channels of the metasurface structure according to the control signal. In this way, the metasurface structure can be flexibly adjusted, so that the metasurface structure can dynamically adapt to different working environments and requirements, and the calculation process and sending process of the control signal can be simplified to improve work efficiency.

[0037] In one possible implementation, please refer again to Figure 2 The control interface 100 may further include a mode setting area 120 .

[0038] Please refer to Figure 3 , step S130 may include the following sub-steps.

[0039] Step S131 , in response to a user operation, obtaining a control mode input by the user in the mode setting area 120 .

[0040] Step S132: in the first mode, directly generate the control signal according to the first parameter.

[0041] Step S133: in the second mode, adjusting the first parameter to obtain a second parameter, and generating the control signal according to the second parameter.

[0042] In this embodiment, the first mode may be a single mode, and the second mode may be a scanning mode. If the control mode selected by the user in the mode setting area 120 is the first mode, the control signal may be directly generated according to the first parameter obtained in step S120, and the incident angle and the exit angle in the first parameter remain unchanged. If the control mode selected by the user in the mode setting area 120 is the second mode, the incident angle or the exit angle in the first parameter may be adjusted to obtain the second parameter, and the control signal may be generated according to the second parameter.

[0043] Specifically, when the control mode selected by the user in the mode setting area 120 is the second mode, the incident angle and the exit angle of the metasurface structure can be tested to determine the best incident angle and the best exit angle of the signal.

[0044] In one possible implementation, please refer again to Figure 2 The control interface 100 may further include a parameter adjustment area 130 .

[0045] Please refer to Figure 4 , step S133 may include the following sub-steps.

[0046] Step S133a, in response to the user operation, obtaining the parameter adjustment range input by the user in the parameter adjustment area 130.

[0047] Step S133b: adjust the first parameter according to the parameter adjustment range to obtain a plurality of the second parameters.

[0048] Step S133c: Generate multiple corresponding control signals in sequence according to multiple second parameters.

[0049] In this embodiment, if the control mode selected by the user in the mode setting area 120 is the second mode, the incident angle or the exit angle in the first parameter can be adjusted multiple times according to the parameter adjustment range input by the user in the parameter adjustment area 130, and multiple second parameters can be obtained respectively, and multiple corresponding control signals can be generated in sequence according to the multiple second parameters. The client can send down multiple times different control signals obtained according to different second parameters.

[0050] Specifically, the incident angle or the exit angle in the first parameter can be automatically adjusted according to the parameters such as the starting angle, the ending angle, the step size, and the scanning interval set by the user in the parameter adjustment area 130, wherein the starting angle can represent the scanning starting value of the incident angle or the exit angle, for example, if the starting angle is set to 0°, the scanning process will start from 0°; the ending angle can represent the scanning ending value of the incident angle or the exit angle, for example, if the ending angle is set to 90°, the scanning will continue until 90°; the step size can represent the incremental value of each adjustment of the incident angle or the exit angle, for example, if the step size is set to 10°, the angle is adjusted by 10° each time from the starting angle to the ending angle until the ending angle is reached; the scanning interval can represent the time interval for each transmission by the client.

[0051] In some examples, when the incident angle is set, the starting angle of inci_AZ can be set to 10°, the ending angle of inci_AZ can be set to 16°, the step size of inci_AZ can be set to 2°, the starting angle of inci_EL can be set to 10°, the ending angle of inci_EL can be set to 13°, the step size of inci_EL can be set to 1°, and the scanning interval can be set to 1s. Therefore, when the client sends the second parameter for the first time, the corresponding inci_AZ in the second parameter is 10° and inci_EL is 10°. When the client sends the second parameter for the second time, the interval between the second sending and the first sending is 1s, and the corresponding inci_AZ in the second parameter is 12° and inci_EL is 11°. When the incident angle reaches the ending angle, the sending stops.

[0052] In addition, please refer again Figure 2 The control interface 100 may further include an execution button. After the user inputs the control mode in the mode setting area 120, the control signal may be generated and issued by clicking the execution button. If the control mode selected by the user is the second mode, after the user inputs the parameter adjustment range, the execution button may be clicked to sequentially generate and issue multiple control signals.

[0053] The control interface 100 may further include a historical data recovery area. When the control mode selected by the user is the first mode and the execution button is clicked to generate the control signal, the historical data recovery area may automatically record the current first parameter. At the same time, by selecting the first parameter recorded in the historical data recovery area, the first parameter may be restored to the parameter setting area 110, without the user having to re-enter the first parameter in the parameter setting area 110.

[0054] In a possible implementation manner, when the first parameter is adjusted according to the parameter adjustment range, the incident angle or the emergent angle in the first parameter may be adjusted in sequence according to the parameter adjustment range.

[0055] In this embodiment, if the control mode selected by the user in the mode setting area 120 is the second mode, the user can choose to adjust the incident angle or the exit angle in the first parameter. For example, the starting angle, the ending angle and the step length of the incident angle can be set in the parameter adjustment area 130, and the starting angle, the ending angle and the step length of the exit angle can also be set in the parameter adjustment area 130.

[0056] In a possible implementation, the metasurface structure may include a plurality of surface units distributed in an array, and each of the surface units may include a plurality of voltage channels. Figure 2 The control interface 100 may further include an installation and setting area 140 .

[0057] Please refer to Figure 5 , the control method of the super surface structure may also include the following steps.

[0058] Step S210 , in response to a user operation, obtaining the number and order of the surface units input by the user in the installation setting area 140 .

[0059] Step S220: Generate a corresponding control signal according to the number and sequence of the surface units.

[0060] In this embodiment, if the number of the surface units is different, the number of the voltage data in the control signal is different; if the order of the surface units is different, the order of the voltage data in the control signal is different; if the spatial position of the surface units is different, the value of the voltage data in the control signal is different. Therefore, if the user selects different numbers and orders of the surface units in the installation setting area 140, the generated control signal is different.

[0061] The number of the voltage data in the control signal may be equal to the product of the number of the surface units and the number of voltage channels of one of the surface units.

[0062] An embodiment of the present application also provides a control method for a metasurface structure, which is applied to a control system of the metasurface structure. The control system of the metasurface structure may include a client and a metasurface structure.

[0063] Please refer to Figure 6 , the control method of the super surface structure may include the following steps.

[0064] In step S310 , the client provides a control interface 100 , and the control interface 100 includes a parameter setting area 110 .

[0065] In this embodiment, step S310 and Figure 1 Corresponding to the step S110, for the specific description of step S310, please refer to the description of step S110.

[0066] Step S320: the client responds to the user operation and obtains the first parameter input by the user in the parameter setting area 110, where the first parameter includes the incident angle and the exit angle of the metasurface structure.

[0067] In this embodiment, step S320 and Figure 1 Corresponding to the step S120, for the specific description of step S320, please refer to the description of step S120.

[0068] Step S330: The client generates a control signal according to the first parameter, wherein the control signal includes voltage data corresponding to each voltage channel of the metasurface structure.

[0069] In this embodiment, step S330 and Figure 1 Corresponding to the step S130, for the specific description of step S330, please refer to the description of step S130.

[0070] Step S340: the client sends the control signal to the metasurface structure.

[0071] In this embodiment, step S340 and Figure 1 The step S140 corresponds to the above, and for the specific description of step S340 , reference may be made to the description of step S140 .

[0072] Step S350: the metasurface structure adjusts voltage data corresponding to each voltage channel of the metasurface structure according to the control signal.

[0073] In this embodiment, the client refers to the end that sends the control signal, and the client may include a mobile terminal device, such as a smart phone, a personal computer (PC), a tablet computer, etc. The metasurface structure refers to the end that receives the control signal.

[0074] In a possible implementation manner, the control signal may include a frame header, a frame tail, and voltage data.

[0075] In some examples, if the number of voltage channels corresponding to each surface unit is 128, the control signal received by the super surface structure can be 204, X1.1, X1.2...X1.128, X2.1...Xn.128, 238, 10, wherein 204 represents a frame header, 238 and 10 represent a two-byte frame tail, X1.1-Xn.128 represent voltage data, and n represents the number of surface units. For example, if the value of X1.1 is 153, the voltage value of the corresponding voltage channel is 15.3V.

[0076] Please refer to Figure 7 , step S350 may include the following sub-steps.

[0077] Step S351, determining whether the frame header and frame tail of the control signal are correct.

[0078] Step S352: If correct, adjust the voltage data corresponding to each voltage channel of the metasurface structure according to the voltage data of the control signal.

[0079] In this embodiment, after the metasurface structure receives the control signal, the frame header and frame tail of the control signal can be first determined. If the frame header and frame tail of the control signal received by the metasurface structure are correct, the voltage data of the control signal can be identified, and the voltage data corresponding to each voltage channel of the metasurface structure can be adjusted according to the voltage data of the control signal.

[0080] In a possible implementation, the metasurface structure may include a plurality of surface units.

[0081] Please refer to Figure 8 , step S350 may include the following sub-steps.

[0082] Step S353: The first surface unit receives the control signal sent by the client, and sends the control signal to the next surface unit.

[0083] Step S354: The i-th surface unit receives the control signal sent by the i-1-th surface unit, and sends the control signal to the i+1-th surface unit, where i is greater than or equal to 2.

[0084] In this embodiment, after the first surface unit of the supersurface structure receives the control signal sent by the client, the first surface unit can obtain part of the voltage data in the control signal and send the rest of the voltage data in the control signal to the next surface unit.

[0085] In some examples, if the number of voltage channels corresponding to each surface unit is 128 and the number of surface units is 9, the control signals received by the super surface structure may be 204, X1.1, X1.2…X1.128, X2.1…X9.128, 238, 10, and the first surface unit may control the voltage values ​​of each voltage channel of the first surface unit in sequence according to the voltage data X1.1…X1.128 in the control signal, and send the voltage data X2.1…X9.128 in the control signal to the next surface unit.
