摘要

设计了一种基于超材料的微波频段宽带吸波器。吸波器采用典型的三层结构, 顶层和底层为金属层, 中间层为介质层。顶层是在单个单元上利用多个吸收峰叠加原理设计的由圆形开口环和方形开口环组合而成的金属结构。仿真结果表明, 该吸波器在10.65~22.39 GHz频率范围内的吸收率大于90%, 半峰全宽为13.07 GHz, 相对半峰全宽为83.7%;吸波器整体厚度仅为中心波长的1/10。

Abstract

A novel broadband absorber in microwave frequency band based on metamaterials is designed, which is a typical three-layer structure with top and bottom layers of metal and the middle layer of dielectric. The top layer is a metal structure which is designed on a single cell by using the principle of multiple-absorption-peak superposition and composed of a circular open ring and a square open ring. The simulation results show that the absorptivity of the proposed absorber is over 90% in the frequency range of 10.65-22.39 GHz, the full width at half maximum (FWHM) is 13.07 GHz, and the relative FWHM is 83.7%. The overall thickness of this proposed absorber is only about 1/10 of the center wavelength.
