摘　　要：根据相位匹配条件,推导了平面电磁波斜入射情形下分层有耗手征介质中本征波复数波矢量的实部和虚部,二者方向不同使得在介质中传播的本征波为非均匀平面波.然后通过波矢量实部确定了介质中本征波的折射角.最后根据边界条件和本征波场方程给出了分层有耗手征介质中斜入射电磁波的传播矩阵,该传播矩阵可用于解析分析任意入射角情形下分层手征介质的反射透射和电波传播特性.The real and imaginary parts of the eigen complex wave vector in a stratified lossy chiral medium for the case of oblique incidence are derived by using the phase-matching condition.Due to the fact that the real and imaginary parts are nonparallel,the eigen wave propagating in the medium is inhomogeneous.Then the refraction angle of the eigen wave can be deduced via the real part of the wave vector.Finally the propagation matrix of the obliquely incident wave in a stratified lossy chiral medium is derived based on the boundary conditions and the field equations of eigen wave in each region.By using the proposed method,the reflection,transmission,and propagation characteristics of plane wave with arbitrary incident angle in a stratified chiral medium can be analyzed.
