Analysis of multiconductor transmission lines with frequency-dependent parameters and incident electromagnetic fields

This paper presents an efficient algorithm for transient analysis of multiconductor transmission lines (MTL) with frequency-dependent parameters subjected to electromagnetic interference (EMI). A closed-form formulation in terms of split representation of equivalent sources is proposed to account for EMI induced effects. A compact and passive macromodel based on delay extraction and closed-form representation is used to describe the distributed nature of the MTL stamp. The proposed algorithm, while guaranteeing the stability of the simulation by employing passive macromodels, provides significant speed-up for EMI analysis of transmission line networks, especially with large delay and low losses.
