Analysis of Excited Multiconductor Transmission Lines Based on the Passive Method of Characteristics Macromodel

This paper presents a time-domain macromodel for lossy multiconductor transmission lines exposed to electromagnetic interference. The proposed algorithm is based on the recently developed passive method of characteristics, which provides an efficient mechanism to ensure the passivity of the macromodel for different line lengths. Numerical examples illustrate that when compared to other passive incident field coupling algorithms, the proposed method is efficient in modeling electrically long interconnects since delay extraction without segmentation is used to capture the frequency response.
