Frequency domain simulation of lossy multiconductor transmission lines

In this paper, we present the behaviour of the lossless and lossy multiconductor transmission lines in frequency domain. This study is based on a characteristics method, this method is permits modeling the line as a quadripole whose advantage is not to presuppose applied charges conditions in its extreme. This permits it to be introduced easily in the circuit simulators as Spice, Esacap and Saber. Diverse examples of applications, in the literature, are presented to validate these method and to show their interests and to understand the behaviour of a line MTL in the frequency domain.
