宽带高效反射电磁波极化调控超表面的实验研究
Experimental demonstration of broadband and high-efficiency reflection polarization conversion metasurface
摘要
Abstract
Metasurface has opened an effective way to handle the polarization states of electromagnetic waves since their intrinsic parameters could be flexibly tailored.In this paper,a simple anisotropic metasurface is presented to realize the polarization manipulation of linearly polarized wave with high conversion efficiency in a wide frequency band.The presented simple metasurface is able to convert the linearly polarized incident wave into its orthogonal polarized reflected wave at the frequency range of 8.16～15.32 GHz.Both the simulated and experimental results demonstrate that the bandwidths of the polarization conversion ratio reach more than 90％ with the relative bandwidths of 60％.The conversion mechanism of the polarization is discussed with the theoretical calculations and surface current distributions.关键词
