摘要
基于等效媒质理论,分析了近红外波段的石墨烯-电介质多层膜结构双曲超材料(GDM-HMMs)的双曲色散关系,对传输矩阵法(TMM)进行了优化,计算分析了不同周期数下的石墨烯双曲超材料的透射谱。基于法布里-珀罗共振腔(F-P腔),理论分析了透射谱的演变规律,验证了石墨烯双曲超材料在近红外波段的双曲色散关系。研究结果表明,实现电磁波传输需要大切向波矢条件。结构总周期数影响透射谱特性,可用F-P腔理论进行分析和反向结构设计。
Based on the effective medium theory,the hyperbolic dispersion relationship of graphene-dielectric multilayer(GDM)hyperbolic metamaterials(HMMs)in the near-infrared waveband is analyzed.The transfer matrix method(TMM)is optimized.The transmission spectra of GDM-HMMs with different numbers of periods are calculated and analyzed.Based on the Fabry-Perot(F-P)cavity theory,the evolution of transmission spectra is theoretically analyzed,and the hyperbolic dispersion relationship of GDM-HMMs in the near-infrared waveband is verified.The research results show that the large tangential wave vector condition is needed for the realization of electromagnetic wave transmission in GDM-HMMs.The transmission spectral characteristics are influenced by the total number of structural periods,and the F-P cavity theory can be used for the analysis and reverse structural design.
