摘要

本文提出了一种新型的基于弯曲线超表面的线圆极化变换器。所提出的超表面是由介电衬底分隔的两个金属层组成的二维周期性结构。每个单元的结构都是弯曲的线条,在顶部和底部的金属层上印刷。通过控制入射波垂直和水平电场分量的相位,使入射波穿过超表面后,两个分量的相位差为90°。该超表面将线极化波转换为圆极化波,带宽为10.5~11.5 GHz。仿真结果表明,该超表面在偏振转换方面具有一定的应用价值。

Linear-to-Circular Polarization Converter Based on Meander-line Metasurfaces
In this paper, a novel linear-to-circular polarization converter based on meander-line metasurfaces is presented. The proposed metasurfaces is a two-dimensional periodic structure which consists of two metallic layers separated by dielectric substrate. The structure of each unit is meander-line which is printed on the top and bottom metallic layers. By controlling different phase for vertical and horizontal electric field components of incident wave, the phase difference is 90° between two components, after passing through the metasurfaces. The metasurfaces converts the linear polarization wave to circular polarization wave with the bandwidth of 10.5~11.5 GHz. The simulation results show the metasurfaces is valuable for polarization conversion application.
