摘要：
This paper presents a ultra-thin chessboard-like metasurface, whose arrangement is optimized to reduce both monostatic and bistatic radar cross-section (ReS) in a wide band. The optimized metasurface is formed by two kinds of lattice structures. The wideband monostatic ReS reduction is obtained by properly selecting the phase curve of both structures. Lattices of the metasurface are arranged in an optimized fashion, distributing the scattered energy to more directions and contributing to the great bistatic ReS reduction. The monostatic ReS reduction larger than 10dB has been obtained over more than 80% frequency bandwidth.
