摘要

液晶材料在微波频段具有良好的调制特性，在微波可调谐器件领域具有巨大的应用潜力。本文针对液晶材料微波介电常数的测量需求，提出了一种基于人工局域表面等离激元谐振的传感器。通过设计环形谐振器结构，在sub-6 GHz频段形成局域表面等离激元窄带谐振峰。通过给液晶施加外加电场，能够实现对液晶介电常数的调控。通过谐振频点位置的拟合，能够得到对应的液晶的介电常数大小，从而实现液晶材料在微波频段的介电常数的测量。本文研究了不同液晶层厚度、不同液晶介电常数对人工局域表面等离激元谐振频点的影响。随着液晶层厚度增加或者液晶介电常数的减小，谐振频点,f,1,和,f,2,都逐渐增大。当液晶层厚度大于或等于0.5 mm时，谐振频点,f,1,和,f,2,随介电常数的变化具有良好的线性度，且具有高灵敏度（,>,400 MHz/Δ,ε,），远大于基于目前报道的其他形式介电常数传感器。同时，本传感器结构可以在液晶层上下施加电场，从而实现在不同外加电场作用下液晶材料微波介电常数的测量，在液晶微波特性研究领域具有应用潜力。

Abstract

Liquid crystal materials have good modulation characteristics in the microwave band， and have great potential for application in the field of microwave tunable devices. In this paper， a sensor based on the resonance of spoof localized surface plasmon is proposed for the demand of microwave dielectric constant measurement of liquid crystal materials. The ring resonator structure is designed to form narrow-band resonant peaks in the sub-6 GHz band with localized surface surface plasmon. By applying an applied electric field to the liquid crystals， the modulation of the liquid crystal dielectric constant can be achieved. The corresponding dielectric constant can be obtained by fitting the position of the resonant frequency points， thus realizing the measurement of the dielectric constant of the liquid crystal material in the microwave band. The effects of different liquid crystal layer thicknesses and different liquid crystal dielectric constants on the resonant frequency points of the spoof localized surface plasmon are studied. The resonant frequency points ,f,1, and ,f,2, increase gradually with the increases of the liquid crystal layer thickness or the decreases of the liquid crystal dielectric constant. When the thickness of liquid crystal layer is equal or greater than 0.5 mm， the resonant frequency points ,f,1, and ,f,2, have good linearity with the change of the liquid crystal dielectric constant. The proposed sensor has a high sensitivity （,>,400 MHz/‍Δ,ε,）， which is much larger than that based on other forms of dielectric constant sensors reported so far. At the same time， this sensor structure can apply electric field above and below the liquid crystal layer， thus realizing the measurement of microwave dielectric constant of liquid crystal materials under the action of different applied electric fields， which has potential for application in the field of microwave characterization of liquid crystals.
