椭圆偏振光在各向异性1维光子晶体中的传输

为了解决利用传统传输矩阵法计算在各向异性材料结构中任意极化态电磁波传播遇到的困难,设计含磁光材料缺陷层的1维光子晶体。通过把入射电磁波按左旋圆偏振和右旋圆偏振进行正交分解的方法,推导出适合各向异性材料和任意极化态入射电磁波的传输矩阵算法。结果表明,该算法可以确定1维层状结构透射波和反射波偏振态的变化。

Transmission of elliptically polarized waves through 1-D anisotropic photonic crystals

In order to overcome the difficulties of transmission calculation of arbitrary polarized electrical-magnetic waves passing through anisotropic materials by means of the traditional transfer matrix, 1-D photonic crystal with magnetic defect was designed. After incident elliptically polarization wave is decomposed into left-handed and right-handed circular polarized waves, a transfer matrix for dealing with anisotropic material and arbitrary elliptically polarization was deduced. The result indicates that the change of polarization states of reflected and transmitted waves from 1-D photonic crystal can be determined by means of this new method.
