本文研究了由单壁碳纳米管（CNT）森林组成的新型开口环谐振器（SRR）超材料的形状相关中红外特性。引入差距和凹陷形状的闭环几何形状减少了15%的总反射率，由于在SRRs中的圆形电流和LC谐振的产生。SRR高度的增加使总红外反射率降低了25%。碳纳米管独特的一维各向异性电学和光子学特性，结合SRR电路中诱导的人工折射率，将刺激新的光电子应用的发展。(C)2020年美国光学学会根据OSA开放获取出版协议的条款
In this work, shape-dependent mid-infrared properties of novel split ring resonator (SRR) metamaterials composed of single-walled carbon nanotube (CNT) forest are investigated. The introduction of the gap and dip shape to the closed ring geometry reduced the total reflectance by 15%, due to the generation of circular currents and LC resonances in SRRs. The increase of the SRR height reduced the total IR reflectance by 25%. Unique one-dimensional anisotropic electric and photonic properties of CNTs, combined with an artificial refractive index induced in SRR circuits, will stimulate the development of new optoelectronics applications.
