| 摘 要： | 格林函数问题是讨论点源激励的辐射问题。本文从格林函数的概念出发,讨论了格林函数非齐次标量Helmholtz方程'2φ(r'→) k2φ(r'→)=-P(εr'→)的求解,同时利用并矢概念引入了并矢格林函数,对非齐次矢量方程××Ee→-k2Ee→=iωμJ→的求解进行了讨论,从结果来看,格林函数和并矢格林函数的引入,给复杂电磁问题的讨论带来了极大方便。

| Abstract: | Green's function is generally used to discuss the problem of incentive radiation of point source.In this paper on the basis of Green's function it discusses solution of the Green's function of non-homogeneous scalar Helmholtz equation by using the dyadic concept and discusses the non-homogeneous vector's equation.As a result,it proves the introduction Green's function and dyadic Green's function,brought great convenience in discussing the complex issues of electromagnetic. |
