【摘要】 基于多屏耦合形式和级联结构,本文提出了一种中心频率为0.3THz的宽带频率选择表面设计。利用等效电路模型分析了该单元FSS的频率响应特性,通过全波仿真软件CST分别研究了入射波角度和极化方式对该结构频率响应特性的影响,结果显示其在0.17-0.42THz内具有小于0.5dB的插入损耗,并且在0-45°入射角范围内具有较好的稳定性以及对极化方式不敏感的特点。更多还原

【Abstract】 Based on the multi-screen coupling form and cascade structure,this paper proposes a broadband frequency selective surface design with a center frequency of 0.3 THz.The equivalent circuit model is used to analyze the frequency response characteristics of the unit FSS.The effects of the angle of the incident wave and the polarization mode on the frequency response characteristics of the structure are studied by the full-wave simulation software CST.The results show that it has an insertion loss of less than 0.5 dB in 0.17-0.42 THz,and has good stability and insensitivity to polarization mode in the range of 0-45 ° incident angle.更多还原
