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。
A complete and detailed derivation of the electric field, the magnetic field spectral domain and the space-domain Green’s function produced by z, φ and ρ-direction electric dipole in cylindrical layered media is provided in order to provide accurate analysis of the cylindrical conformal microstrip antenna by using the moment method The theoretical basis. In addition, based on the literature [2-6], a new numerical method for fast calculation of Green’s function of cylinder stratified media is proposed. The numerical results show the correctness of the formula and the superiority of the improved method.
