摘　　要：太赫兹指波长处在0.03至3mm范围内的电磁波,目前处在5G/6G通讯波段,具有广宽的应用前景.光子晶体是一种人工电磁周期介质,具有色散小等特性,两者优点结合起来,通过光子晶体设计可以达到对太赫兹波的调制,从而达到设计太赫兹波调制器的目的,为太赫兹5G/6G通讯器件提供参考.研究二维结构光子晶体太赫兹波禁带特性,研究多角度结构变化对禁带特性的影响以及对正方晶格结构形成缺陷模拟禁带特性,得出多角度结构和缺陷态结构都对形成太赫兹禁带有一定的影响,这些变化对太赫兹在正方晶格光子晶体中的传输起到调制作用.Terahertz is an electromagnetic wave with wavelengths ranging from 0.03to 3mm.At present,it is in the 5G/6G communication band and can be better used in the future communication system.Photonic crystal is a kind of artificial electromagnetic periodic medium,which has the characteristics of small dispersion and so on.Combined with the advantages of the two,the modulation of terahertz wave can be achieved by photonic crystal design,and the purpose of designing terahertz wave modulator can be achieved,which provides a reference for terahertz 5G/6G communication device.Both multi-angle structure and defect state structure have some influence on the formation of terahertz band gap,and these changes play a modulation role in the transmission of terahertz in square lattice photonic crystals.
