摘要

本文设计了一种基于液晶(LC)的可调谐带阻频率选择表面(FSS)。FSS是一个夹层结构，包含两个反对称金属层，由LC分开。通过改变偏置电压，LC的相对介电常数可控制在2.5 ~ 3.3之间。仿真结果表明，FSS在17.938 GHz ~ 20.152 GHz范围内具有连续可调谐特性，其中可调谐范围为11.63%。

Wideband Tunable Bandstop Frequency Selective Surface Based on Liquid Crystal

In this paper, a tunable bandstop frequency selective surface (FSS) is designed based on liquid crystal (LC). The FSS is a sandwich structure, which contains two antisymmetric metallic layers, separated by LC. The relative permittivity of LC can be controlled between 2.5 and 3.3 by changing bias voltage. The simulation results show that continuous tunable feature of the FSS is obtained, from 17.938 GHz to 20.152 GHz, of which the tunable range is 11.63%.
