A method is developed for analyzing the time-domain response of systems consisting of an arbitrary number of multiconductor transmission lines which are mutually interconnected and terminated by arbitrary linear networks. The lines can be lossy and they can have frequency-dependent parameters. The system can be excited by an arbitrary number of generators, which are located in the terminal and interconnecting networks. The time-domain waveforms of the generators are first Fourier transformed. The analysis of the system is performed in the frequency domain at a set of discrete frequencies. Finally, the inverse fast Fourier transform is used to obtain the time-domain waveforms. The transmission-line analysis is based on the modal theory in the frequency domain. Numerical examples are presented to illustrate the application of the present technique. The examples include single multiconductor transmission lines, cascaded lines, branchings, and loops formed by transmission lines.
