摘要
本文提出一种新型的三频超材料吸波体,该吸波体由FSS阵列、介质层和金属背板组成,利用组合法使两种单元在电磁波激励下呈现出不同频点的谐振特性,其厚度相较于传统吸波材料有较大改善。结果表明:该吸波体在3.39GHz、4.94GHz和9.91GHz,分别实现98.9%,97.6%和98.4%的吸收率,对不同的极化方向和角度入射呈现不敏感性。
In this paper we present a novel triple-band metamaterial absorber,which is composed of a FSS array and a metal ground separated by a dielectric spacer.By employing the hybrid method,the two unit cells with different electromagnetic resonance have been achieved.The metamaterial absorber is much thinner than the conventional one.The results reveal that the absorption rates of proposed absorber respectively are 98.9%,97.6% and 98.4% at 3.39,4.94,9.91 GHz.The above presented metamaterial absorber is insensitive with the polarization of the incident waves and can perform well in a wide range of incident angles.
