摘要：
yIn this paper, we proposed and demonstrated a broadband back radar cross section (RCS) reduction metasurface by integrating polarization conversion and scattering cancellation. A broadband polarization conversion structure was designed based on split ring. We used 4*4 array of split ring structure and its mirror-symmetric structure as the super-cell units to construct a metasurface with chessboard structure. The metasurface can efficiently reduce the co-polarization back RCS for all azimuth angles of incident wave. The metasurface sample with optimized structure parameters was fabricated and measured. The measured -10dB back RCS reduction band of the metasurface is from 8.7 to 16.4 GHz.
