ABSTRACT
A novel ultra-wideband (UWB) metasurface has been proposed to realize radar cross-section (RCS) reduction based on double layer chessboard structured polarization conversion metasurface (PCM). The “bow-shaped” unit cell consists of three split rings and one strap, which can produce five resonance points to improve the bandwidth of convert linear polarized waves into their orthogonal polarized ones. The structure has an ultra-wideband linear polarization conversion efficiency with at least a 90% polarization conversion ratio (PCR) from 7.3 to 26.1 GHz. Using the proposed cell and its mirror cell to form a chessboard structured metasurface, and comparing it with a metal surface of the same size, the obtained simulation results show that the proposed metasurface realizes a 10dB monostatic RCS reduction from 7.3-25.8 GHz.
