| 摘 要： | 利用异向介质吸收器的传输线模型及CST仿真软件对其太赫兹波段的宽频吸收特性进行了研究。结果表明：异向介质吸收器对太赫兹电磁波的吸收主要来源于开口环共振单元(SRR)的LC共振。提出了两种使异向介质吸收器获得宽频太赫兹吸收的方法：一是增加LC共振中的等效电阻R，能有效扩展吸收带宽到100GHz以上；二是通过优化具有双吸收...

| Abstract: | Using the transmission line model of the metamaterial absorber,its broadband absorption behavior in the terahertz(THz) regime was studied with CST simulating software.The results show that the THz electromagnetic wave absorption of the metamaterial absorber mainly comes from the LC resonance of the split-ring resonator(SRR).Two methods are proposed to make the metamaterial absorber achieve broadband THz absorption.The first method is to increase the equivalent resistance R in the LC resonance,which extends ... |
