Dynamic RCS Reduction Performances of Antenna Array with Coding Metasurface

Figure 6

Simulated scattering results of different layouts; (a) reference antenna (when all PIN diodes are of “ON” or “OFF” states, here just take all “ON” states as an example); (b) checkerboard layout; (c) new chessboard layout; (d) “0101” square ring nested layout; (e) monostatic RCS variation curves with frequency; (f) bistatic RCS changing curves with angle.
