Multiconductor transmission line scattering parameters in time domain

In the paper, we present a fast and effective calculation method of coupled interconnect S-parameters. The paper presents an approach based on the method of successive approximations, but taking into account the dependence on the frequency of line parameters. The concept is to use the rational approximation of the matrix of per-unit-length parameter of the line calculated for each frequency. In our approach, we calculate the scattering parameters of an n-wire transmission line.
