摘要

In this paper, a polarization conversion unit is designed as the coding unit. The units are arranged in a regular cross-arrangement. Convolution operation is composed of the Dirac-delta function and the principle of scattering-pattern shift. The Dirac-delta is optimized by generalized Snell's law and addition theorem. According to the convolution operations, the cross-arrangement pattern is shifted to multiple directions to reduce the backscattering field. Compared with regularly arranged metasurface, this method can reduce the radar cross section (RCS) of single station by at least 10dB. Compared with the traditional intelligent optimization algorithm, this method provides a new route to reduce RCS by random distribution of elements.
