Abstract

Abstract : This study presents an analysis of time‐domain crosstalk between two parallel coaxial cables from 10 MHz − 1 GHz. Although such coupling has been extensively studied in the frequency domain, it is advantageous to evaluate the coupling in the time‐domain for the analysis of signal integrity‐related issues. The near‐end crosstalk is modelled using one dimensional transmission line modelling (TLM) approach, which is validated against practical measurements and commercial simulation software. A prony approximation method and equivalent circuit approach were used to account for frequency‐dependent parameters such as surface transfer impedance and skin effect in the TLM simulations.
