含左手材料的康托多层结构

Cantor Multilayers Made of Materials with Negative Refractive Index

采用转移矩阵的方法研究了由左手材料和右手材料交替组成的康托结构的透射谱,发现相比于全部由右手材料组成的康托多层结构的透射谱,其透射峰的个数减少,但是随着康托结构代数的增加,这种现象逐渐消失。在康托多层结构中,场强的分布呈现出与结构相似的现象。本文同时研究分析了康托结构中的零有效折射率带隙。

Transfer matrix method was used to analyze the transmission spectra of cantor structure containing positive and negative refractive index materials. The perfect transmission peaks reduce comparing with the purely positive refractive index cantor muhilayers structure in this research was found. But with the generation increasing, this difference will disappear. The field intensity are studied and show lattice-like distribution. We also investigate and analyzed the property of the zero-band gap of the cantor structure.
