一维各向异性光子晶体的带隙结构和传输特性

Band Structure and Propagation Properties of One-dimension Anisotropy Photonic Crystals

研究了由两种不同的各向异性材料交替排列而构成的一维人工周期结构材料的带隙结构和传输特性.各向异性和复式结构导致了x偏振和y偏振有不同的带隙结构、透射率和态密度等.研究发现,当两种材料的各向异性常量、厚度满足一定条件时,能带结构中会出现缺隙现象.

The band gap and propagation properties are studied for one-dimension photonic crystals that are made by alternately arranging two different anisotropy dielectric materials. The anisotropy arid duplex result in different band gap structures, transmission probabilities and state densities for x polarization and y polarization. It is interesting that gap vanishing occurs when anisotropy constants and thicknesses of two materials satisfy certain condition.
