Metasurface regulation and control method of transmission array antenna

The invention discloses a metasurface regulation and control method of a transmission array antenna. According to the method, design of high aperture efficiency and low sidelobe characteristics is achieved through phase modulation of the two electromagnetic metasurface planes, Chebyshev radiation field aperture distribution required by the low sidelobe characteristics is achieved through phase modulation of the first metasurface plane, and meanwhile energy loss is avoided in the design process of the low sidelobe characteristics through phase control. Therefore, the characteristic of high aperture efficiency is realized. And the second electromagnetic metasurface plane realizes a high-gain antenna beam through phase modulation and controls the pointing direction of the whole antenna beam, so that the required radiation direction is realized. According to the method, the energy loss generated in the method for designing the low side lobe characteristic in the related technology can be avoided, so that the high
