摘要
提出了一种新型宽带反射极化转换超表面.该超表面由周期性排列的单元结构组成,单元结构是以斜对称图案的金属开口环、介质基板以及金属背板组成.通过uv分解示意图和HFSS软件仿真分析,在9.2～18 GHz频段内,此超表面能够实现线电磁波的交叉极化转换,平均转换效率超过95％,相对带宽达到64.7％.
Abstract
A novel wideband reflective polarization conversion metasurface is proposed.The meta-surface is composed of a periodically arranged unit structure,which is composed of a metal open ring with an oblique symmetrical pattern,a dielectric substrate and a metal back plate.Through the uv decomposition diagram and HFSS software simulation analysis,the metasurface can realize the cross polarization conversion of linear electromagnetic wave in the frequency band of 9.2～18 GHz,and the average conversion efficiency is more than 95％,as well as the relative bandwidth rea-ches 64.7％.
