基于金属线阵列嵌入的低频宽带电路模拟吸波体设计
Design of a low-frequency broadband circuit analog absorbers based on wire media∗
摘要
Abstract
A circuit analog absorber (CA) with wire medium is presented. Both the original CA and the structure presented are analyzed. It is shown that original CA cannot have more than one resonant frequency in low frequency band, owing to the limitation by the effective resistance. The presented structure breaks the limitation using artificial plasma resonance, with the wave dispersion in the structure analyzed using the quasi-static model. The experimental results, consistent with simulation results based on the finite-difference time-domain (FDTD) method, show that the structure obtains dual-band absorption, thus broadening the absorption band in low frequency band.关键词
