消光定理与电磁波在两半无限各向异性磁电材料间的传播
Extinction theorem and propagation of electromagnetic waves between two semi-infinite anisotropic magnetoelectric materials
摘要:
基于分子光学理论,研究了电磁波在两个半无限大各向异性磁电材料之间的反射和折射。根据赫兹矢量和叠加原理,推广了消光定理,导出了波的传播特性。利用这些结果,我们可以很容易地解释布儒斯特效应的物理起源。我们的结果将消光定理推广到两种任意各向异性材料间的波传播,所用方法也可应用于材料中波传播的其它问题,如光的光的散射。
英文摘要:
Based on molecular optics we investigate the reflection and refraction of an electromagnetic wave between two semi-infinite anisotropic magnetoelectric materials. In terms of Hertz vectors and the principle of superposition, we generalize the extinction theorem and derive the propagation characteristics of wave. Using these results we can easily explain the physical origin of Brewster effect. Our results extend the extinction theorem to the propagation of wave between two arbitrary anisotropic materials and the methods used can be applied to other problems of wave propagation in materials, such as scattering of light.
