摘　　要：基于圆柱坐标系中圆柱矢量波函数,研究自由空间圆柱并矢格林函数。将其应用于导体圆柱空间推证出了导体圆柱的第一、二类电型并矢格林函数,并就这些函数的关系做了分析。推得的电型并矢格林函数可为并矢格林函数方法处理圆柱型导体电磁散射等问题提供研究方法和理论依据。Based on the cylindrical vector wave functions in the cylindrical coordinate system,the first and second types of electric dyadic Green’s functions of the conductor cylinder were proved through studying the free space cylindrical dyadic Green’s functions and applying the functions to the space of the conductor cylinder.And the relationships of these functions were analyzed.The electric dyadic Green’s functions derived from above analysis can provide research method and theoretical basis for using DGF method to deal with electromagnetic scattering of cylindrical conductors.
