我们提出了一种多层互补的超材料结构上的晶体石英基板测量100和700 GHz之间。这种结构实现了二阶太赫兹带通滤波器的概念，并且它提供了上级品质因数、裙部陡度和带外抑制。对品质因数和插入损耗的物理限制也进行了研究，包括金属的趋肤深度和石英中的光学声子共振。基于这些因素，设计了一系列高频滤波器，并给出了仿真结果。(C)2011年美国光学学会
We propose a multilayer complementary metamaterial structure fabricated on a crystal quartz substrate measuring between 100 and 700 GHz. The concept of a second-order terahertz bandpass filter is realized by this structure, and it offers a superior quality factor, steepness of skirts, and out-of-band rejection. Physical limitations on the quality factor and insertion loss have also been studied, including the skin depth of the metal and the optical phonon resonance in quartz. Based on these factors, a series of higher frequency filters has been designed, and simulation results are presented. (C) 2011 Optical Society of America
