Abstract

In this paper, we present a lightweight, broadband metamaterial absorber that exhibits polarization stability and is insensitive to incident angles. The absorber is composed of one layer of indium tin oxide impedance surface, three layers of quartz fiber composite material, and one layer of paper honeycomb on a metal sheet. Our proposed absorber has a 90 % absorptivity bandwidth of 13.19 GHz, ranging from 4.83 GHz to 18.12 GHz at TEM plane wave normal incidence, covering the entire X and Ku band. We illustrate the variation of design parameters and the distribution of electromagnetic field and current to investigate the absorption mechanism. To demonstrate the effectiveness of our design, we fabricate a prototype sample and measure its absorption performance. The results show a bandwidth of 12.38 GHz, ranging from 4.91 GHz to 17.29 GHz, with a low profile of 0.095λL at the lowest operating frequency. The experimental results are in good agreement with the numerical simulation, effectively verifying our proposed design.

基于 ITO 阻抗膜的轻质宽带超材料吸收器

本文介绍了一种轻质宽带超材料吸收器，它具有极化稳定性，对入射角度不敏感。该吸收器由一层氧化铟锡阻抗面、三层石英纤维复合材料和一层金属板上的纸蜂窝组成。我们提出的吸收器具有 13.19 GHz 的 90 % 吸收带宽，在 TEM 平面波法线入射时，吸收带宽从 4.83 GHz 到 18.12 GHz 不等，覆盖了整个 X 和 Ku 波段。我们说明了设计参数的变化以及电磁场和电流的分布，以研究吸收机制。为了证明设计的有效性，我们制作了一个原型样品，并测量了其吸收性能。结果表明，该器件的带宽为 12.38 GHz，范围从 4.91 GHz 到 17.29 GHz，在最低工作频率时的轮廓较小，仅为 0.095λL。实验结果与数值模拟结果十分吻合，有效验证了我们提出的设计方案。
