摘要

在本文中，我们建议抑制超表面不希望的色散以扩大其工作范围，同时保留所需的色散以保持功能。如图所示，通过反向叠加（RS）方法，我们在大角度（≥60°）双波段EM窗口的超表面上实现了该思想。超表面原本只适用于横向电（TE）极化，并且具有窄有效带（EB）。但通过选择性色散抑制，可实现RS后的双极化双宽带工作。

A Selective Dispersion–Suppressed Metasurface for Dual-Polarization and Dual-Broadband Electromagnetic Window at Large Angles

In this manuscript, we propose to suppress the metasurface's undesired dispersion to widen its working range, while preserving the desired one to preserve the function. As shown in the figure, through a method of reversed superimposition (RS), we have implemented the idea on a metasurface for the dual-band EM window at large angles (≥ 60°). The metasurface is originally only for transverse electric (TE) polarization and has a narrow effective band (EB). However, through selective dispersion suppression, it can work for dual polarization and dual broadband after the RS.
