| 摘 要： | 本文利用矢量波函数变换方法讨论了两媒质半空间的电磁散射问题，从Ｍａｘｗｅｌｌ方程出发，讨论了单矩法在三维复杂形体散射问题上的实施。并在数学球面上将内部区域的有限元解与外部区域矢量波函数变换的结果相匹配，从而得到复杂埋入体的电磁散射特性。作为检验和示例，本文计算了在平面波照射下自由空间导体球，埋入导体球，埋入介质覆盖钝锥等的散射场，其中一些结果与可供比较的经典解或其它算法的结果进行了比较，吻合较好。

| Abstract: | The vector wave function expansion combined with the unimoment method is applied to calculate the scattered fields of buried objects of arbitrary shape or of inhomogeneous material.Computational examples,for the excitation of the incident plane wave,are given for the case of free conducting sphere,buried conducting sphere and buried dielectric covered obtuse cone,Results of computation bear out the vahdity of the technique. |
