A new modal analysis theory for multiconductor nonuniform transmission-line structures: application to the analysis of line junctions

This paper is the second part of a two-paper set concerning a generalized modal analysis approach to the study of multiconductor nonuniform transmission-line structures. In the first part, a very detailed theoretical analysis was developed aimed at establishing the foundations of the method. Here, numerical results are presented for the purpose of illustrating the various steps involved in the application of the new modal technique. To demonstrate the effectiveness of this new analysis method an example of a nonuniform structure, comprising the junction of two chain-connected power lines with different cross sections, is considered. The frequency-dependent propagation properties of such a structure are evaluated, the computation results revealing that important resonance phenomena take place at certain critical frequencies.
