摘　　要：在PartⅠ的基础之上,详细、完整地推导出有关z、φ和ρ方向电偶极子圆柱分层介质的3种不同形式的混合位格林函数。分析了这3种格林函数的特点,从而为利用混合位积分方程(MPIE)准确分析圆柱共形微带天线提供了理论基础。通过与文献[2]、[3]给出的混合位格林函数的比较,说明了本文公式的正确性,最后,通过Mat-lab仿真,成功计算了文献[8]中的圆柱分层介质的第一类混合位格林函数。Basing on Part Ⅰ of this paper, three different kinds of mix - potential Green ＇ s function due to z-、φ- andρ - oriented electric sources embedded in cylindrically stratified media are deduced in detail and then their characteristics are analyzed. So, they provide the fundamental theory for the accurate analysis of cylindrically conformal microstrip antenna using mixed potential electrical field integral equation （MPIE）. Comparing the formulations of mixed potential Green＇ s function provided in the paper with those provided in references [ 2 ] [ 3 ], the validity of the formulations is proved. At last, the first kind mixed potential Green＇s function of the cylindrically stratified media in reference [ 8 ] is calculated accurately through Matlab simulation.
