In this paper, a simple design strategy is proposed for obtaining broadband, polarization insensitive metasurface, for radar cross section (RCS) reduction. Two different unit cells, circular patch and square ring structures are chosen as basic meta-atoms. For significant enhancement of RCS reduction bandwidth, sixteen supercells comprised of the variation of the two unit cells are distributed randomly in a checkerboard setting, resulting in a diffused backward scattering. The proposed metasurface have a wide-band, polarization insensitive RCS reduction spectra. © 2019 IEEE.
