一、引言 TEM传输线的特性阻抗,除了少数特定的规则截面形状的传输线可用精确解析式进行计算外;一般的任意截面形状的传输线只能进行不同程度的近似计算。无论精确计算或近似计算,通常都是针对所给定传输线截面形状建立特定数学模型,然启再进行计算的。这样的计算公式,往往都因截面形状而异,缺乏适用于任意截面形状的统一数学物理方法。本文讨论用矩量法求解任意截面形状的TEM传输线的特性阻抗问题。从原则上讲,这种方法可以求解任意截面形状的TEM传输线的特性阻抗,并能达到满足工程
I. INTRODUCTION The characteristic impedance of a TEM transmission line, except for a few specific regular cross-sectional transmission lines, can be calculated with an exact analytical formula. A general transmission line of arbitrary cross-sectional shape can only be approximated with different degrees of approximation. Regardless of the exact calculation or approximate calculation, usually for a given transmission line cross-section shape to establish a specific mathematical model, and then start the calculation. Such calculation formulas often depend on the cross-sectional shape, and lack a uniform mathematical physics method suitable for any cross-sectional shape. This paper discusses the problem of the characteristic impedance of a TEM transmission line with arbitrary cross-sectional shape using the moment method. In principle, this method can solve the characteristic impedance of the TEM transmission line of any cross-sectional shape, and can meet the engineering
