摘要
从各向同性,均匀无源区域电磁场的矢量波函数展开式出发,利用标准与非标准球矢量波函数之间的转换关系、场型分析、广义索末菲积分得到了两媒质半空间散射场表达式。并讨论了平面波照射下埋入球的散射。与单距法结合就可求解任意形状不均匀结构埋入体的散射问题。
The expressions of scattering field in two-medium half-spaces are derived by means of the conversion relations between the standard and nonstandard spherical vectdr wave functions, generalized Sommerfeld integrals and analysis of field type, and based upon the vector wave function expansions of electromagnetic field in isotropic homogeneous source-free region. With this technique accompanied with the unimoment method present a technique to solve scattering problems of arbitrarily-shaped inhomogenous buried objects.
