摘要
本文对光轴任意取向各向异性超常介质涂层平板镜像波导的横电波(TE模)的特性进行了细致分析与推导,得到了特征方程及其色散关系式,以及时间平均坡印亭矢量式,并进行了相应的数值模拟,描绘出它们各自的特性曲线,得出光轴任意取向各向异性超常介质涂层平板镜像波导的模式,既不同于各向同性左手介质涂层中的,也不同于各向同性常规介质层的导波特性。
Guidance characteristics in anisotropic metamaterial for arbitrary orientation of optical axis slab mirror waveguides a/e analyzed. The mode characteristics equations and the dispersion relations of the transverse electrical modes（TE） are obtained. The expressions of their Poynting vector are obtained too. Several lower -order transverse electrical modes （TE） are calculated numerically and the dispersion curves are obtained. Some abnormal properties of guided modes in anisotropic metamaterial for arbitrary orientation of optical axis slab mirror waveguides are discussed.
