摘　　要：完整、详细地推导了圆柱分层介质中由z、φ和ρ方向电偶极子产生的电场、磁场的谱域、空域格林函数,从而为利用矩量法准确分析圆柱共形微带天线提供了理论基础。另外,在文献[2-6]的基础上提出了一种稳定性好的快速计算圆柱分层介质格林函数的数值分析方法。数值计算结果说明了本文公式的正确性及改进后方法的优越性。Spectral and spatial green＇s function of electric and magnetic fields due to z-, ψ- and ρ-oriented electric sources embedded in cylindrically stratified media are deduced in detail. It provides the fundamental theory for the accurate analysis of cylindrically conformal microstrip antenna using MoM. In addition, a more robust method of fast calculating green＇ s function for cylindrically stratified media is proposed basing on the references [ 2-6 ] with comparing to the traditional methods. At last, numerical result proves the validity of the formulations provided in this paper and shows the advantages of the improved method.
