A Metasurface with Phase and Magnitude Modulation Function

In this paper, a 1 bit programmable metasurface is designed, which can control the amplitude and phase by optimizing the encoding method. Firstly, the working principle of metasurface for RCS (Radar Cross Section) reduction is demonstrated, and the designed coding metasurface is simulated and analyzed. Then the amplitude and phase manipulation are simulated by MATLAB and CST respectively. The simulation results show that different coding sequences have a good effect on the reduction of RCS, and can achieve the dual regulation of amplitude and phase. As a result, this kind of coding metasurface is expected to further improve the stealth performance of the target.
