摘要
新型人工电磁材料,不同于传统材料,是由单元电磁结构进行周期排列而成,其最大的特点就是可以通过改变单元的结构参数来改变其等效电磁参数如介电常数和磁导率等。本文介绍了一种基于新型人工电磁材料的双极化平板式吸波结构,通过吸波材料的设计原则分析了结构式吸波材料的原理及优势,并通过仿真软件着重分析和对比了影响该结构吸波性能的重要参数。最后在此双极化结构的基础上,提出了双频带设计方案,并且分析了影响其特性的参数。
Different from the traditional materials, metamaterial is a series of artificial materials based on periodic inclusions of metals and/or dielectrics which exhibits controllable electromagnetic charateristics. In this paper a dual-polarization absorbing metamaterial is presented. The important parameters of structures which affect the ability of absorbing are analyzed through simulation software. What is more, a method to realize the dual-frequency comprising the dual-polarization absorbing structure is presented.
