Extension of the “Equivalent Cable Bundle Method” for Modeling Crosstalk of Complex Cable Bundles

Abstract

The so-called equivalent cable bundle method which has been successfully used in modeling the electromagnetic (EM) immunity and emissions of complex cable bundles is further studied and applied in the computation of the EM crosstalk between two different cables in a single cable bundle or in two cable bundles. The cable can be the type of single wire, twisted pair, shielded wire, or any other kind. By grouping together the conductors according to their terminal load configuration, the complexity as well as the computation time for the complete cable bundle modeling has been significantly reduced and fairly good precision is maintained. Different from the method used in immunity and emission problems, a modified five-step procedure is established to define the electrical and geometrical characteristics of the reduced cable bundles. Numerical simulations performed on simple and complex cable bundles are given to validate the efficiency and advantages of the method. This paper is considered as a new step in the study of crosstalk between two cables in a single cable bundle and in two cable bundles.
