In this paper, a simple design strategy is presented for designing broadband, polarization insensitive metasurface for radar cross section (RCS) reduction. Two different unit cell structures, circular patch, and loop are chosen to enhance the phase bandwidth. Different phase gradient supercells are designed by positioning these unit cells in a specific phase gradient direction. The eight supercells are then randomly distributed in a checkerboard pattern for further diffusing the incident wave. The proposed metasurface significantly reduce the RCS and demonstrate features such as polarization insensitivity and wideband operational bandwidth. © 2019 IEEE.
