摘要
In this paper, two novel artificial magnetic conductor (AMC) structures are designed to realize 180 degrees of phase difference in a wideband frequency. These two AMC structures are encoded as unit "0" and unit "1", respectively. By using Simulated Annealing algorithm, the coding sequences of the coding metasurface can be designed, so that the radar cross section (RCS) reduction can be realized as well. Compared with the metallic surface, the simulation and measurement results of this presented coding metasurface indicate that this coding metasurface can reduce RCS significantly under normally incident electromagnetic (EM) waves from 7 GHz to 20 GHz, so the bandwidth is 96.3%, and the RCS under obliquely incident waves also can be dramatically reduced as well. Furthermore, the RCS reduction of this coding metasurface is better than that of traditional chessboard surface.
