Abstract

A novel method named equivalent current density based on finite element method was developed for parametric variation problem of signal transmission caused by the external environment. According to the investigation on circuit parameters measurement

multiconductor model of transmission cable is established

and the induction voltage and the redistribution character of current density at the conductor cross-section caused by the eddy current are also discussed. The new formulas of resistance and inductance are derived based on the equivalent current density and parameters exaction is realized with the finite element method

which demonstrates validation of the method for extracting transmission parameters.And the increased signal frequency leads to the corresponding increase of AC resistance and power consumption.The resistance and inductance manifest the frequency-dependent characters linearly varying within some frequency bands.
