| 摘 要： | 利用有限元中的一种新型矢量元——“边元”的概念，给出了计算三维电磁散射问题时的一种新方法——矢量吸收边界条件与边元法结合．这种方法与传统的方法相比具有求解变量少、计算精度高等特点．通过对典型算例的计算，且与矩量法的结果进行对比，验证了文中算法的有效性，尤其是对分层媒质的问题，这种算法的优越性更为突出

| Abstract: | An edge element method combined with vector absorbing boundary conditions is presented for 3 D scattering problems. The method is more accurate and efficient compared with nodal element method. The advantages of this approach are particularly significant for multilayer dieletricobatacles. The typical numerical examples are shown the paper. It is a promising method for 3 D EM nurmerical problems. |
