Abstract
In this paper, an analysis method for multiconductor-transmission-line (MTL) systems by applying modal decomposition and Kirchhoff's circuit laws is proposed. By defining the input impedance matrix in each section of the structure, this method can be applied to the cases in which number of conductor changes, or additional terminations are included. Following the flowchart, the modal current as well as the line voltage/current can be all obtained. Two structures are simulated for validation, where good agreement can be seen in both the cases. This analysis method can be applied to estimate voltage/current distribution, crosstalk, and mode conversion, which is helpful to solve the signal integrity (SI) and electromagnetic interference (EMI) problem when designing.
