| 摘 要： | 本文利用矢量波函数展开法求解了任意激励原埋入体的电磁散射问题。通过导出圆柱和圆球矢量波函数的转换关系,使场量满足分界平面和数学球面边界条件,从而方便地利用矢量波函数展开求解了这一复杂边值问题。作为示例,本文计算了在平面波和偶极子激励下,埋入导体球和介质球的散射场。

| Abstract: | An analysis of solving the electromagnetic scattering by buried objects using the vector vvave function expansion is presented. For expanding the boundary conditions both on the planar air-earth interface and on he spherical surface, the conversion relations be-tween the cylindrical and spherical vector wave functions are derived. Hence the vector wave function expansion is conveniently applied to solve this complex boundary value problem. For the excitation of the incident plane wave and the dipole above the earth, the scattering patterns of the buried conducting and dielectric sphcres are presented and discussed. |
