Wang Hui-qin, Zhengdong Liu, Yingmao Xie, Xuwei Wang

Abstract

The transfer matrix of negative refractive index medium (NIM) layer and positive refractive index medium (PIM) layer are derived from Maxswell equation. And the optical properties of an all-dielectric photonic crystal with NIM-PIM alternant multilayer and a photonic crystal with PIM-PIM alternant multilayer are studied by the means of transfer matrix method. We simulated and compared the corresponding characters of them. The results show that the photonic crystal with NIM-PIM alternant multilayer has broader reflection band and very narrow band gap, and it has better angular property than that of ordinary photonic crystal.
