摘　　要：基于圆柱坐标系中的圆柱矢量波函数,将自由空间圆柱并矢格林函数应用于介质圆柱并推证出了介质圆柱内外的第三类电型并矢格林函数,该研究结论可为并矢格林函数方法处理圆柱形介质电磁散射等问题提供理论依据和技术支撑.In this paper,based on the cylindrical vector wave functions in the cylindrical coordinate system,the third-kind electric dyadic Green′s functions inside and outside the medium cylinder are deduced by applying the free-space cylindrical dyadic Green′s function to the cylinder medium.Research results can provide theoretical basis and technical support for the dyadic Green′s functions method to deal with the electromagnetic scattering problems of cylindrical media.
