| 摘 要： | 本文利用矢量场的辐射边界条件(Radiation Boundary Condition,简称RBC)推导出矢量场的一阶辐射条件算子,并介绍了该算子在三维电磁散射计算中的应用。文中应用该算子在散射体表面的性质,近似计算了理想导电圆球的表面感应电流分布和雷达散射面积。数值计算结果与级数展开解一致性较好。

| Abstract: | The vector on-surface radiation condition (VOSRC)operator is derived for computing the three-dimensional electromagnetic scattering from a perfectly conducting sphere. The Current distribution and the bistation radar cross-section (RCS) of the spheres with different radius are given, though the former on surface have obvious errors, the latter in far-field region are in good agreement with the exact solutions. |
