Pixelated Checkerboard Metasurface with a Simplified Design Method

A pixelated checkerboard metasurface with a simplified design method is proposed in this paper. By optimizing the design process, the pixelated checkerboard metasurface contains only one type of artificial magnetic conductors (AMCs). This simplified design method can reduce the optimization time of traditional pixelated checkerboard metasurface to half. In addition, this paper optimizes the distribution position of AMCs and proposes a triangular distribution to improve the final radar cross section (RCS) reduction effect compared to the traditional checkerboard distribution. RCS reduction compared to a perfect electronic conductor (PEC) surface of 10dB is from 3.9GHz to 10.3GHz. RCS reduction compared to a checkerboard surface of 5dB is from 8GHz to 9.2GHz.
