| 摘 要： | 本文利用Wilcox的矢量场渐近展开式将三维矢量边界条件应用于散射表面上,从而获得一个计算三维电磁散射问题的新方程。应用该公式计算得到了不同尺寸导电圆球上感应电流分布的数值结果。计算结果表明,利用该公式所得结果与准确的级数展开解有着良好的吻合。

| Abstract: | In this Paper, a three-dimensional vector boundary condition applying to the surface of scatterer is used to formulate a new 3-D OSRC based on an Wilcox's asymptotic expansion, for solving electromagnetic scattering from a perfectly conducting body. Numerical results of the current distribution on conducting spheres with different sizes are given, which are in accordance with the exact solutions. |
