An ultra-wideband 2-bit coding metasurface using Pancharatnam-Berry phase for radar cross-section reduction
文献摘要：
An ultra-wideband 2-bit coding metasurface is designed for radar cross-section(RCS)reduction.The design process is presented in detail,in which a polarization conversion metasurface(PCM)is first proposed.The proposed PCM can realize ultra-wideband circular polarization(CP)maintaining reflection.Moreover,Pancharatnam-Berry(PB)phase will be generated in the co-polarized reflection coefficient by rotating the metallic patches in its unit cells.Thus,based on the PCM,the four coding elements of a 2-bit coding metasurface are constructed using PB phase,and an ultra-wideband PB 2-bit coding metasurface is proposed according to an appropriate coding sequence.The simulated and experimental results show that the coding metasurface has obvious advantages of wideband and polarization-insensitivity.Compared to a metallic plate of the same size,it can achieve more than 10 dB RCS reduction in the frequency band from 9.8 GHz to 42.6 GHz with a relative bandwidth of 125.2％under normal incidence with arbitrary polarizations.
