摘要

考虑了偏心分层球和无限圆柱的散射。对于介质平板波导,本文还讨论了导模在非均匀性下的散射问题。对于介电球(圆柱)内嵌有球(圆柱)非均匀性的情况,结合球矢量波(圆柱波)的平动加法定理,采用了分离变量法。另一方面,对于介质板波导内部的非均匀性散射问题,采用了包含适当格林函数的积分方程。

Scattering of Plane and Guided Waves from Composite Dielectric Bodies
Scattering from eccentrically stratified spheres and infinite cylinders is considered. For a dielectric slab waveguide the scattering of a guided mode froman internal cylindrical cal inhomogeneity is also treated. For the case of a spherical (cylindrical) inhomogeneity embedded inside a dielectric sphere(cylinder) the method of separation of variables is used in conjuction with translational addition theorems for spherical vector waves(cylindrical waves). On the other hand, an integral equation involving the appropriate Green's function is employed for the problem of scattering from inhomogeneities inside a dielectric slab guide.
