摘　　要：由于基本矢量波函数基本性质的不同导致三种格林函数方法在解决电磁边值问题时存在差异,一般有磁型、电型、位型格林函数方法.使用这三种方法求解矩形波导的格林函数,通过比较分析得出G_(m)方法比G_(e)和G_(A)方法在解决电磁场边值问题时较为简单方便,因此在处理电磁边值问题中获得了较为广泛的应用.Due to the different basic properties of the basic vector wave functions,several Green's function methods are different in solving the electromagnetic boundary value problems.In this paper,three Green's function methods of magnetic type,electrical type and potential type are used to solve the Green's functions of rectangular waveguide.Through comparative analysis,it is found that method is simpler and more convenient than and methods in solving the boundary value problems of electromagnetic fields,so it has been widely used.
