| 摘 要： | 提出一种快速分析柱面共形微带结构的高效率迭代方法。基于传输线理论与快速模式变换理论的方法通过在圆柱形分界面上引入横电磁波的概念代替以往的切向电磁场,加快了计算过程。由混合模式基函数表征圆柱分层介质中的横电磁波,最终推导出模式导纳算子和谱域反射算子的具体形式。并运用波概念迭代过程计算出了带线馈电的圆柱面共形微带天线的表面电场及表面电流,在此基础上,进一步得到了天线的输入阻抗,通过与参考文献结果的对比,证明了该方法的准确性与高效性。

| Abstract: | An efficient iterative method is presented for fast analysis of cylindrically conformal microstrip structure. Based on the transmission line modeling (TLM) method and the fast mode transform (FMT) theory,this method accelerates the process of the calculation by introducing the concept of the transverse electromagnetic waves instead of the transverse fields considered in the traditional algorithm. In the cylindrically stratified media,the transverse electromagnetic waves are represented by mixed modal basis ... |
