摘要

作为基于本征函数解的全域数值边界条件（ＧＮＢＣ）的自然发展，本文从电磁场等效原理出发，提出了第二类ＧＮＢＣ－２的理论和算法．实际上，采用第二类ＧＮＢＣ－２的有限元解法，是有限元解法与积分方程矩量解法的结合，特别适合于复杂目标散射特性分析，本文限于讨论二维问题，并给出若干典型计算实例．

Abstract

As the natural development of the eigen-function Global Numerical Boundary Condition （GNBC）.the non-eigen-function GNBC is presented.In this paper the GNBC of second kind is deduced from the EM Equivelence Principle and formally evaluated by moment method（NM）solutions of equivelent source intesral equations. In this sence

the GNBC based finite element（FE）solutions are actully the hybrid solutions of the MM and FF

hence they are inherently the very generalized numerical procedure for the complicated EM boundary value problems.Three typical application examples to open-region EM problems are given for demonstration.
