[Figure 6] This is a schematic diagram of a reflect array and a target signal hot zone, illustrated according to one embodiment of the present invention. [Modes for carrying out the invention]

[0022] Figure 1 is a schematic diagram of an electronic device 100 with a reflect array, illustrated according to one embodiment of the present invention. The electronic device 100 includes a processor 110, a storage medium 120, and a communication interface 130.

[0023] The processor 110 is, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose microcontroller unit (MCU), microprocessor, digital signal processor (DSP), programmable controller, application-specific integrated circuit (ASIC), graphics processing unit (GPU), image signal processor (ISP), image processing unit (IPU), arithmetic logic unit (ALU), complex programmable logic device (CPLD), field programmable gate array (FPGA), or other similar components, or a combination of the above components. The processor 110 is coupled to a storage medium 120 and a communication interface, and accesses and executes multiple modules and various application programs stored in the storage medium 120.

[0024] The storage medium 120 is, for example, any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory, hard disk, solid state drive (SSD), or similar component, or a combination of the above components, and is used to store multiple modules or various application programs that can be executed by the processor 110.

[0025] The communication interface 130 transmits or receives signals wirelessly or via a wired connection. The communication interface 130 can further perform operations such as low-noise amplification, impedance matching, frequency mixing, frequency up or down conversion, filtering, amplification, and similar operations. For example, the processor 110 communicates with the reflect array via the communication interface 130 and transmits signals to the reflect array, thereby configuring delay compensation for each reflect unit in the reflect array.

[0026] Figure 2 is a flowchart illustrating a method for configuring a reflect array based on one embodiment of the present invention, which may be carried out by the electronic device 100 shown in Figure 1. The reflect array may include a plurality of reflect units. When an incident signal reaches a reflect unit, the reflect unit can delay the generation of a reflected signal corresponding to the incident signal. In other words, the reflect unit can provide a time delay between the incident signal and the reflected signal. The reflect unit may be a delay-tunable reflect array, and the reflect unit may be a single cell in the delay-tunable reflect array. For example, the reflect unit may include an electromagnetic wave reflect array, an antenna electrode, or a tuning electrode as described in U.S. Patent No. 12,107,332. It should be noted that the term "distance" as used herein refers to, for example, an actual distance, a normalized distance generated by normalizing the actual distance of the wavelength based on the operating frequency, or electrical length, and is not limited thereto.

[0027] In step S201, the processor 110 may acquire the incident signal features of the designed incident signal and the reflected signal features of the designed reflected signal (for example, via the communication interface 130). The reflect array is configured to receive the target incident signal and reflect the target reflected signal corresponding to the target incident signal. The incident signal features or reflected signal features may include, but are not limited to, wavefront (e.g., plane wave or non-plane wave), polarization, or frequency.

[0028] In step S202, the processor 110 may determine the geometric shape type of the virtual reflecting surface based on the incident signal characteristics and the reflected signal characteristics. Specifically, the processor 110 may generate a first determination result by determining whether the target incident signal is a plane wave based on the incident signal characteristics, and generate a second determination result by determining whether the target reflected signal is a plane wave based on the reflected signal characteristics. The processor 110 may determine the geometric shape type of the virtual reflecting surface based on the first determination result and the second determination result.

[0029] If the first judgment result and the second judgment result are different (i.e., one of the target incident signal and the target reflected signal is a plane wave, and the other of the target incident signal and the target reflected signal is a non-plane wave), the processor 110 may determine that the geometric shape type of the virtual reflecting surface is a parabolic surface, or one or more parabolas contained within the parabolic surface. The processor 110 may configure a reflect array based on the parabolas.

[0030] If the first and second judgment results are identical and both are non-plane waves, the processor 110 may determine that the geometric shape type of the virtual reflecting surface is an ellipsoid or one or more ellipses contained within the ellipsoid. The processor 110 may then construct a reflect array based on the ellipses.

[0031] If the first and second judgment results are identical and both are plane waves, the processor 110 may determine that the geometric shape type of the virtual reflecting surface is a plane, or one or more straight lines that the plane contains. The processor 110 may configure the reflect array based on the straight lines. Table 1 shows examples of geometric shape types of virtual reflecting surfaces. Table 1

[0032] [Table 1]

[0033] In step S203, the processor 110 may configure a virtual reflective surface based on the incident signal characteristics and the reflected signal characteristics, and the virtual reflective surface may intersect with at least one of the multiple reflective units in the reflect array.

[0034] In step S204, the processor 110 may configure a plurality of reflection units by determining delay compensation for at least some of the plurality of reflection units based on the incident signal characteristics, the reflected signal characteristics, and the geometric shape type.

[0035] Taking a virtual reflecting surface containing a parabola as an example, Figure 3 is a schematic diagram of a virtual reflecting surface containing a parabola A, illustrated according to one embodiment of the present invention. If one of the target incident signal and the target reflected signal is a non-plane wave, the other of the target incident signal and the target reflected signal can be a plane wave. The embodiment in Figure 3 is, JPEG2026110474000052.jpg1066 is a non-plane wave, and While it is assumed that JPEG2026110474000053.jpg1266 is a plane wave, the present invention is not limited to this.

[0036] If the target incident signal is a non-plane wave, the processor 110 may define the position of the source of the target incident signal (e.g., a non-plane wave) as the origin of the coordinate system (e.g., a three-dimensional coordinate system such as a Cartesian coordinate system). If the target reflected signal is a non-plane wave, the processor 110 may define the target position of the target reflected signal (e.g., a non-plane wave) as the origin of the coordinate system. For example, Figure 3 is Assuming that JPEG2026110474000054.jpg1066 is a non-plane wave, processor 110, The source S of JPEG2026110474000055.jpg1066 may be defined as the origin O. A person skilled in the art, based on the reciprocal characteristics of electromagnetic waves, may define the focal point of the reflected signal as the origin O when the incident signal is a plane wave (from an unrestricted distance) and it is necessary to focus the reflected signal to a single point.

[0037] The Y-axis of the coordinate system may be parallel to the plane wave. For example, Figure 3 is Assuming that JPEG2026110474000056.jpg1266 is a plane wave, processor 110 determines the Y-axis of the coordinate system It can be defined as being parallel to JPEG2026110474000057.jpg1266.

[0038] In this embodiment, k is the index of each individual reflection unit in the reflect array, where k is a positive integer and The image is JPEG2026110474000058.jpg1251, where M is the total number of reflective units in the reflect array. If it is JPEG2026110474000059.jpg1023, then processor 110 will determine the non-plane wave (for example, based on the origin O) JPEG2026110474000060.jpg1066) and The intersection with JPEG2026110474000061.jpg1385 is It can be determined that this is JPEG2026110474000062.jpg1288, and here, The file is JPEG2026110474000063.jpg1144, The file is JPEG2026110474000064.jpg1155. JPEG2026110474000065.jpg1011 shows the location of the source or target of a non-plane wave and one of the reflecting surfaces on the RFA. Between JPEG2026110474000066.jpg1385 This is the normalized distance generated by normalizing JPEG2026110474000067.jpg1229 (for example, source S and Between JPEG2026110474000068.jpg1266 JPEG2026110474000069.jpg1134, or source S and JPEG2026110474000070.jpg1385 Between JPEG2026110474000071.jpg12126 It approximates JPEG2026110474000072.jpg1232, and the signal is divided by the wavelength in the surrounding environment at the point of reflection. JPEG2026110474000073.jpg109 is a non-plane wave (for example, JPEG2026110474000074.jpg1066) and The angle of incidence (or first reflection angle, for example, between JPEG2026110474000075.jpg1385) and the first reflection angle, The normal vector of JPEG2026110474000076.jpg1266 and The angle between JPEG2026110474000077.jpg1066 and JPEG2026110474000078.jpg109 is a plane wave (for example, JPEG2026110474000079.jpg1266) and The reflection angle between JPEG2026110474000080.jpg1385 (or referred to as the second reflection angle, for example, The normal vector of JPEG2026110474000081.jpg1266 and This is the angle between JPEG2026110474000082.jpg1266 and the original image.

[0039] In one embodiment, as index k increases, the corresponding JPEG2026110474000083.jpg1166 and a source or target of a non-plane wave (for example, This indicates that the distance between the source S) of JPEG2026110474000084.jpg1066 and the source is increasing. In other words, JPEG2026110474000085.jpg1166 is the reflecting unit closest to the source or target of the non-plane wave among the M reflecting units, and JPEG2026110474000086.jpg1167 is the reflecting unit furthest from the source or target of the non-plane wave among the M reflecting units.

[0040] Processor 110 is, The parabola A of the virtual reflective surface can be determined based on JPEG2026110474000087.jpg11106, and among them, parabola A is JPEG2026110474000088.jpg1385 It is acceptable to interact with JPEG2026110474000089.jpg11106. Specifically, processor 110, JPEG2026110474000090.jpg11106 and Based on JPEG2026110474000091.jpg1130, It is acceptable to determine that JPEG2026110474000092.jpg11101 is correct. In other words, The distance between JPEG2026110474000093.jpg11106 and the directrix L1 is effectively It is equal to JPEG2026110474000094.jpg1011. Then, the processor 110 sets the origin O as the focus, and Based on JPEG2026110474000095.jpg11101, You may generate JPEG2026110474000096.jpg12148.

[0041] After generating parabola A, processor 110: Based on JPEG2026110474000097.jpg129, The slope of JPEG2026110474000098.jpg1385 It can be determined that it is JPEG2026110474000099.jpg1022. Processor 110, JPEG2026110474000100.jpg1150 and Based on JPEG2026110474000101.jpg11106, You may generate JPEG2026110474000102.jpg12118. All For JPEG2026110474000103.jpg1251, JPEG2026110474000104.jpg1166 is It may be positioned above JPEG2026110474000105.jpg12118.

[0042] Regarding JPEG2026110474000106.jpg1166, the signal source and JPEG2026110474000107.jpg1166 Given that JPEG2026110474000108.jpg1157 is already known, the processor 110 sets the origin O as the center of the circle and Virtual circle C with radius set to JPEG2026110474000109.jpg1128. k The virtual circle C may be generated. k and JPEG2026110474000110.jpg12118 may have a maximum of two intersections. Processor 110 from the two intersections Select the one that is relatively close to JPEG2026110474000111.jpg13116. Represents the location of JPEG2026110474000112.jpg1166 It's fine to name it JPEG2026110474000113.jpg1245, and here, The file is JPEG2026110474000114.jpg1158, JPEG2026110474000115.jpg1013 is a non-plane wave and The angle of incidence between JPEG2026110474000116.jpg1166 and JPEG2026110474000117.jpg1114 is a plane wave and This is the reflection angle between JPEG2026110474000118.jpg1166. In other words, let's assume the two intersection points are P and P'. Intersection point P and The distance between JPEG2026110474000119.jpg14136 and the intersection point P' is The distance between this file and JPEG2026110474000120.jpg14136 is less than the distance between these two files.

Something relatively close to JPEG2026110474000297.jpg1128 It can be named JPEG2026110474000298.jpg1229. In other words, the two intersection points are JPEG2026110474000299.jpg1011 and Let's assume the filename is JPEG2026110474000300.jpg1012. The coordinates on the X-axis in the coordinate system of JPEG2026110474000301.jpg1229 and The distance between JPEG2026110474000302.jpg1128 and this file is: The coordinates on the X-axis in the coordinate system of JPEG2026110474000303.jpg1130 and The distance between this file and JPEG2026110474000304.jpg1128 may be less than this.

Processor 110, By transmitting JPEG2026110474000324.jpg1061 to the reflect array, You may construct the file JPEG2026110474000325.jpg1166. JPEG2026110474000326.jpg18136

[0058] In one embodiment, if the first determination result and the second determination result are the same and both are non-plane waves (i.e., both the target incident signal and the target reflected signal are non-plane waves), the processor 110 receives the source of the target incident signal via the communication interface 130. The target reflected signal reaches the target hot zone via JPEG2026110474000327.jpg1166. The image JPEG2026110474000328.jpg1137 may be obtained.

JPEG2026110474000335.jpg18142

[0059] Figure 5 is a schematic diagram of a reflect array 500 illustrated according to one embodiment of the present invention. The electronic device 100 may be communicated with the reflect array 500 and one or more signal transceivers 610, 620, or 630. The reflect array 500 may include a plurality of reflect units (e.g., reflect unit 510). One or more signal transceivers (e.g., signal transceivers 610, 620, or 630) may be configured to transmit frequency signals to the reflect array 500, causing the reflect array 500 to reflect the frequency signals to the corresponding receiver or target hot zone.

[0060] For example, suppose an electronic device 100 attempts to transmit a signal from a signal transceiver 610 to a distant location via a reflect array 500. The processor 110 may define the signal transceiver 610 as the source location of the target incident signal. The processor 110 may then calculate a parabolic virtual reflecting surface based on the direction of the target location and the position of the signal transceiver 610, using the method described above. Based on the virtual reflecting surface, the processor 110 may configure delay compensation for one or more reflecting units (e.g., reflecting unit 510) in the reflect array 500. After the delay compensation configuration is complete, the processor 110 may control the signal transceiver 610 to transmit a frequency signal to the configured reflecting unit, thereby generating a reflected beam 510 that will be transmitted to the target location by the configured reflecting unit. Similarly, the signal transceiver 610 may be used to receive a signal from a distant location in the direction pointed to by the beam 520 via the reflect array 500.

[0061] Using Figure 6 as an example, assume that the electronic device 100 attempts to transmit the signal from the signal transceiver 620 to a location close to the target hot zone 700 through the reflect array 500. The processor 110 may define the signal transceiver 620 as the source location of the target incident signal. The processor 110 may then calculate a virtual ellipsoidal reflecting surface based on the center point of the target signal hot zone 700 and the position of the signal transceiver 620, according to the method described above. Based on the virtual reflecting surface, the processor 110 may configure delay compensation for one or more reflecting units (e.g., reflecting unit 510) in the reflect array 500. After the delay compensation configuration is complete, the processor 110 may control the signal transceiver 620 to transmit a frequency signal to the configured reflecting unit, thereby generating a reflected beam that converges to the center point of the target signal hot zone 700 by the configured reflecting unit. Similarly, a signal transceiver 620 may be used to receive signals from the center point of the target signal hot zone 700 via the reflect array 500.

[0062] In summary, the electronic device of the present invention can determine how to configure a virtual reflective surface for a reflect array based on the types of target incident and target reflected signals, and can adjust the delay compensation of each reflecting unit in the reflect array based on the virtual reflective surface. The virtual reflective surface may include a parabola, an ellipse, or a straight line. The electronic device can configure the delay compensation of the reflecting units based on the distance between the reflecting unit and the virtual reflective surface. After the configuration of the reflect array is complete, the reflect array reflects plane waves or non-plane waves to predetermined positions, and the reflected signals may be plane waves or non-plane waves.
