本文考虑了两种在频域分析非均匀多导体传输线的方法。第一种是基于均匀线段链矩阵的级联连接。第二种方法是求解空间变线性系统。此外，还提出了在非均匀线模型中引入入射电磁场影响的方法。为了得到时域的解，应用数值拉普拉斯变换（NLT）。分析了几个应用实例，并与ATP/EMTP和其他地方发表的实验测量结果进行了比较。
In this paper, two methods for analyzing nonuniform multiconductor transmission lines in the frequency domain are considered. The first one is based on the cascaded connection of chain matrices of uniform line segments. In the second method, a space-variant linear system is solved. Besides, a technique to introduce the effect of incident electromagnetic fields into the nonuniform line model is presented. To obtain the solution in the time domain, the numerical laplace transform (NLT) is applied. Several application examples are analyzed, and comparisons with the ATP/EMTP and with experimental measurements published elsewhere are provided.
