RCS reduction using nonabsorptive binary structures with anisotropic impedance metasurface

Radar cross section (RCS) reduction using binary structures with non-equidistant matrix arrangement of modules and anisotropic impedance metasurface is presented. The block principle of construction of the binary structures is proposed. Monostatic RCS is reduced on co-polarizations on 15...20 dB in the band 8...16 GHz. Bistatic RCS patterns have no diffraction lobes on co-polarizations. The diffraction lobes on the cross-polarizations in the diagonal planes are lower on 12...29 dB than for the anisotropic chessboard.
