摘　　要：鉴于部分文献关于电型并矢格林函数在矩形波导中的表达式存在缺项.;本文用磁型和电型并矢格林函数法对矩形波导电型并矢格林函数表达式做了详细推证,对缺项产生的来源从几方面做了分析,最后写出了该表达式的完整形式.It is pointed out that there was often a missing term in the expression of electric dyadic Green’s function in rectangular wave guide.In this paper,the electric dyadic Green’s function expression of rectangular wave guide is proved in detail by using magnetic and electric dyadic Green’s function methods,the origin of the missing term is analyzed from several aspects,and the complete form of the expression is written at last.

关 键 词：并矢格林函数法 奇异项 L类矢量波函数 无旋场 本征模式
