THz波段电磁感应透明效应超常媒质的构建

Design of Metamaterial with the Phenomena of EIT in THz

本论文主要对基于金属的一种超常媒质的机理以及相关结构进行研究。在与传统的量子EIT系统的比较中,探索这一现象的激发机理以及验证依据。由左手介质设计的理论基础进行推广,构建并设计了具有电磁感应透明效应的THz超常媒质,对其中的理论问题进行了探讨并对相关材料的定义做出了解释。通过分别对亮部分(内环)和暗部分(外环)进行激发仿真,给出了整体激发的结果。此外,还对探针的位置以及SRR环的厚度分别进行了分析。本研究工作对于推动以金属为基础的光频段材料、结构甚至集成电路、系统的发展和应用具有重要的意义。

This dissertation studies the theorys and structures of a kind of metamaterial which are based on metal.Compared with the traditional EIT system,it tries to do the research on the excitation mechanism and the method to certificate the appearance of the phenomenon.With the help of the other material,metamaterial with the phenomena of EIT in THz is designed and the basic knowledge and defination is also explained.This article also place the research on the excitation of both of the two parts(inner ring and outer ring),and what come next is the whole structure under incident wave.In addition,the research analyses the distribution of probes and the thickness of the rings.These achievements could lead to a number of important fundamental and technological advances in the field of metamaterial of THz.
