摘要

提出了一种超宽带超材料吸收体。它由三层结构组成:一个介电介质在两个金属插入物之间。仿真结果表明，当吸光度达到0.99时，该超材料吸波器的带宽在91.13 ~ 146.13 GHz范围内约为55 GHz。相对带宽比为46%。采用表面微加工技术，可以方便地制备这种复合材料。

An Ultra-broadband Metamaterial Absorber Based on the Square Split Ring

An ultra-broadband metamaterial absorber (MA) is proposed in this paper. It is composed of a three-layer structure: one dielectric medium between two metal inserts. The simulation result shows that the bandwidth of this metamaterial absorber is about 55 GHz from 91.13 GHz to 146.13 GHz when the absorptivity achieves 0.99. The relative bandwidth ratio is 46%. This MA can be easily fabricated by surface micro-machining technology.
