讨论麦克斯韦等式下广义圆极化在手征性媒体中的不同的本构关系.在莱类手征性媒体中广义圆极化波的场,与在非手征性媒体中麦克斯韦等式描述的同构关联有着相同的形式;但是不同的圆极化对应场的物理参数也不同.不管传播方向如何,这样的圃极化波(左或右)传播同等的波数.本文基于球面积分等式研究广义双各向同性物体的电磁散射特征.应用基层顶面等效性原理,能够把在均匀的双各向同性域中的电磁场用分布在它的边界面上的等量电磁流表示出来.

Different constitutive relations of generalized circular polarization in chiml media by using Maxwell's equations are discussed. In a chiral medium for fields with generalized circular polarizations, the Maxwell equations and constitutive relations have the same form in the achiral medium, but the equivalent material parameters differ for field with different circular polarization. Thus a wave of circular polarization (left or right) propagates with the same wave number regardless of its direction of propagation. In this paper, electromngnetic scattering characteristics by general bi-isotropic objects are investigated based on the surface integral equations. By applying the surface equivalent principle, electromagnetic fields inside a homogeneous bi-isotropic region can be represented in terms of equivalent electric and magnetic currents distributed over its boundary surface.
