摘要
采用传递矩阵的方法研究了由正折射率材料和负折射率材料交替排列组成的一维光子晶体结构的透射谱,并对其能带结构和色散关系进行分析,这种正负折射率光子晶体不仅存在一般的布拉格禁带,还存在低频共振禁带.本文也对含左手材料的一维无序结构的局域化进行了分析研究.
Transfer matrix method is used to analyze the transmission spectra of one dimensional photon- ic crystals with negative refractive index material and positive refractive index material alternant struc- ture. The bang gaps and dispersive relation of one dimensional photonic crystal are analyzed. The gener- al Bragg gaps and the resonant gap of low frequency exist in the photonic crystal. We also research local- ization of electromagnetic waves in one-dimension random system containing the left-handed material.
