Abstract

A SPICE circuit model for the evaluation of the effects of the bulk current injection test on coaxial shielded cables is developed. The proposed equivalent circuits do not need the usual subdivision of the circuits in elementary cells, it is valid in both frequency and time domain and is based on the exact solution of the equations stemming from a lossless transmission line model. The intermediate and final results are validated by means of comparison with others, evaluated by independent methods.
