Abstract

In this paper, a structurally simple transmissive all-dielectric metamaterial absorber is designed, fabricated and measured. The unit cell consists of photosensitive resin and water, which the water layers composed of rectangle loop, rectangular block and traffic circle. It achieves over 90% absorption of electromagnetic waves in the frequency range between 11.0 and 27.3 GHz. Meanwhile, three absorption peaks are located at 12.5, 18.4, and 26.0 GHz, which the absorptive are 97.4%, 98.3%, and 98.5%, respectively. In addition, the characteristics of the designed metamaterial reveal wide-incident angle absorption and polarization-insensitive properties. The experimental sample is measured by using the free-space method, and the experimental results are verified to be in well agreement with the simulation data. Observing the distribution of electric and magnetic fields at different resonance frequencies, the physical mechanism of the absorption is attributed to strong magnetic resonance. Therefore, the proposed metamaterial has potential for widespread use in the fields of civilian and military.

全介质水基超材料的超宽带传输吸收能力

本文设计、制造并测量了一种结构简单的透射全介质超材料吸波材料。其单元单元由光敏树脂和水组成，其中水层由矩形环、矩形块和交通圈组成。它在 11.0 至 27.3 GHz 频率范围内对电磁波的吸收率超过 90%。同时，三个吸收峰值分别位于 12.5、18.4 和 26.0 GHz，吸收率分别为 97.4%、98.3% 和 98.5%。此外，所设计的超材料还具有宽入射角吸收和偏振不敏感特性。利用自由空间法测量了实验样品，验证了实验结果与模拟数据十分吻合。通过观察不同共振频率下的电场和磁场分布，可以将吸收的物理机制归结为强磁共振。因此，所提出的超材料具有在民用和军用领域广泛应用的潜力。
