宽带透射吸收极化无关超材料吸波体
A broadband transmission absorption polarization-independent metamaterial absorber
摘要
Abstract
In this paper, we propose a new metamaterial absorber based on magnetic absorbing material. This absorber has the characteristics of low-frequency transmission and high-frequency broadband absorption. The transmission co-efficient of the metamaterial absorber is -0.5 dB at 1 GHz: the good low-frequency transmission property can realize intercommunication between the low-frequency signals. The absorptivity is greater than 80% in the frequency range above 8.4 GHz, which almost covers all the X-band and Ku-band frequencies. In addition, the metamaterial absorber is polarization-independent due to the fourfold rotational symmetry of the unit cell metallic periodic structure. The metamateiral absorber has the advantages of simple design, strong practicability, and high potential application value.关键词
