调制太赫兹范围的多层超材料大带宽阻带过滤器
Tunable broad stop-band filter based on multilayer metamaterials in the THz regime
摘要
设计了金属和介电层的周期性多层结构的大带宽阻带过滤器.三个因素(金属层数,金属层和介电层)对CRR结构的过滤器的阻带和阻带中心频率的影响进行了研究.模拟结果表明阻带带宽可以达到2.2 THz.同时,阻带和中心频率可以通过选择合适的金属层数或者介电层来调制,但它们对金属层的种类并不敏感.
Abstract
A periodic multilayer structure with metal and dielectric layers is proposed to obtain a broad stop-band filter. The influence of three factors (the number of the metal layer (n), the metal layer and the dielectric layer) on the stop-band and central frequency of cross ring resonator (CRR) filter has been investigated. Simulated results indicate that the stop-bandwidth can reach to 2.2THz. Moreover, The stop-band and central frequency can be modulated by selecting appropriate n or dielectric layer, but it is not sensitive to the metal layer.
