摘要

摘要:本文研究了在超表面(MS)顶部附加薄介质层对太赫兹波段电磁波传输的影响。为此，在太赫兹波段设计并分析了基于劈裂环谐振器的质谱。研究了介电常数、膜厚和悬浮高度对s21透射系数特性的影响。为此，建立了数值模型，并采用有限元法进行了求解。进行的研究在三种情况下是有帮助的。首先，改变介电层的悬浮高度可能允许使用MEMS结构可调谐的MSs。此外，这项研究可以用来确定在使用质谱作为传感器来测试可能损坏它的物质时，施加额外的保护层的效果。此外，有一个机会来研究薄膜的介电性质使用所提出的质谱。

Influence of a thin dielectric layer on resonance frequencies of square SRR metasurface operating in THz band

Abstract This article investigates the effect of an additional thin dielectric layer on the top of the metasurface (MS), on the transmission of electromagnetic waves in the terahertz band. For this purpose, the split ring resonator-based MS was designed and analyzed in the terahertz band. The influence of permittivity, film thickness, and suspension height on S 21 transmission coefficient characteristics was studied. For this purpose, a numerical model was created and solved using the finite element method. The conducted study can be helpful in three cases. First, changing the suspension height of the dielectric layer may allow tunable MSs using MEMS structures. Also, this research can be used to determine the effect of applying an additional layer of protection when using the MS as a sensor to test substances that can damage it. In addition, there is an opportunity to study the dielectric properties of thin films using the proposed MS.
