摘　　要：基于圆柱和球坐标系中圆柱和球型矢量波函数,将自由空间圆柱和球型并矢格林函数应用于介质圆柱和球进而推出二者的第三类电型并矢格林函数,并就求解过程特性进行比较分析,其结果可为基于DGF方法处理圆柱和球型介质电磁散射等问题提供理论依据。Based on the cylindrical and spherical vector wave functions in the cylindrical and spherical coordinate systems,applying the free space cylindrical and spherical dyadic Green's functions to medium column and sphere,this paper deduces the third kind of electric dyadic Green's functions of the medium cylinder and sphere and makes a comparative analysis of the characteristics of their solving process.The results can provide theoretical basis for dealing with electromagnetic scattering of cylindrical and spherical media with the DGF method.
