摘要

损耗频率选择表面已被用于设计薄的和宽带的电磁吸收器。FSS的单元格是基于两个同心闵可夫斯基回路。在第一种设计中，闵可夫斯基回路加载了不同配置的集总电阻。在第二个设计中，闵可夫斯基回路是使用电阻片的概念设计的。电阻性闵可夫斯基环路提供2.2GHz至9.4GHz和4.5GHz至17GHz的非常宽的带宽，反射损耗大于10dB。阻性闵可夫斯基回路吸收器的厚度为0.09λ。

Design of broadband electromagnetic absorber using resistive Minkowski loops

Lossy frequency selective surfaces have been used to design thin and broadband electromagnetic absorbers. Unit cell of the FSS is based on two concentric Minkowski loops. In the first design, the Minkowski loops are loaded with lumped resistors in different configurations. In the second design, Minkowski loops are designed using the concept of resistive sheets. Resistive Minkowski loops offer very wide bandwidth from 2.2GHz to 9.4GHz and 4.5GHz to 17GHz for reflection loss greater than 10dB. Thickness of the absorber with resistive Minkowski loops is 0.09λ.
