摘要
基于共模结构的电磁吸波器的研究已经得到了广泛的应用。其中一个根本问题是其性能，特别是带宽响应和吸收特性的不足。本文介绍了基于劈裂环谐振器的超表面x波段吸波器的特性。利用基于srr的超表面材料开发x波段吸波器是为了提高其带宽响应和吸收特性。在0.8 mm厚的FR4环氧介电基片的不同层上，采用由SRR和窄薄条组成的超表面单元格设计了x波段吸波器的结构。采用3.80 mm × 3.80 mm的单元胞尺寸，对所提出的x波段吸波器进行了表征。表征结果表明，单元胞内SRR的分离对x波段吸波器性能的实现起着重要的作用。
Characterization of X-Band Wave Absorber Made of SRR-Based Metasurface
Researches on electromagnetics wave absorber implemented with common pattern structures have been explored for many applications. One of fundamental issues is its insufficiency in the performance, particularly bandwidth response and absorption characteristic. This paper presents the characterization of X-band wave absorber made of metasurface based on split-ring resonator (SRR). The utilization of SRR-based metasurface in the development of X-band wave absorber is intended to enhance its bandwidth response and absorption characteristic. The structure of X-band wave absorber is designed using a unit cell of metasurface composed of an SRR and a narrow thin strip implemented on different layers of 0.8 mm thick FR4 epoxy dielectric substrate. By taking the unit cell dimension of 3.80 mm × 3.80 mm, the characterization of proposed X-band wave absorber is performed. The characterization result shows that the separation of SRR in a unit cell holds an important role in achieving the desired performance of X-band wave absorber.
