【摘要】：结合两个方形封闭谐振环(CRR)嵌套双开口谐振环(SRR)形成新结构,并运用电磁仿真软件研究此结构在太赫兹波段的谐振特性。利用等效电路模型分析谐振峰产生机理;通过观察结构表面谐振电流分布,探究其各个谐振频点出现的原因;分析结构几何参数变化对谐振特性的影响和影响其极化特性的因素。研究表明,这种嵌套环结构分别在1.07THz,1.92THz,3.06THz具有较强的电磁谐振,在一定角度内具有极化不敏感特性。研究结果可为太赫兹波段滤波器,吸波体等器件的设计提供参考。
[Abstract]:A new structure is formed by combining two square closed resonant ring (CRR) nested double open resonant rings (SRRs). The resonance characteristics of the structure in terahertz band are studied by electromagnetic simulation software. The mechanism of resonance peak generation is analyzed by using equivalent circuit model. By observing the distribution of resonant current on the surface of the structure, the causes of the occurrence of each resonance frequency point are explored, and the influence of the structural geometric parameters on the resonant characteristics and the factors affecting the polarization characteristics of the resonant current are analyzed. The nested ring structure has strong electromagnetic resonance at 1.07THzN 1.92THzN 3.06THz and polarization insensitivity at a certain angle. The results can be used as reference for the design of terahertz band filters and absorbers.
