摘要

本文提出了一种由顶层l型和斜杆谐振腔、中层介电层和底层金属板组成的五波段超材料吸波器。对其吸收性能进行了模拟研究。数值结果表明，在正入射下，MA具有5个不同的吸收峰，具有较高的吸光度。研究了吸收机理的损耗特性和场分布。此外，MA超薄且对极化不敏感，因此在大多数实际应用中都很有用。

Design of Ultrathin Five-band Polarization Insensitive Metamaterial Absorbers

A five-band metamaterial absorber (MA) composed of L-shaped and slanting-bar resonators in the top layer, a dielectric layer in the middle and a metallic plate in the bottom is proposed in this paper. Its absorption performance is simulated and studied. Numerical results show that the MA has five distinctive absorption peaks with high absorbance under normal incidence. The loss properties and field distributions are studied to demonstrate the absorption mechanism. Moreover, the MA is ultra-thin and polarization insensitive, and thus be useful in most practical applications.
