A novel approach on multi-shielded coaxial cable immunity assessment based on electromagnetism simulation
Validation de l'immunité des designs de câbles à blindages multiples basée sur la simulation électromagnétique
Résumé
This paper introduces a novel approach for the assessment electromagnetic susceptibility of coaxial cables. In this work, a numerical model of the bulk current injection (BCI) fixture is considered. This fixture injects a current on the shield of the cable in order to produce electromagnetic interferences (EMI) and to extract the shielding features. An efficient and simple model is provided to avoid expensive prototyping steps. In addition, while the noise limits the interpretation of experimental data, the numerical modelling enables the consideration of a clear electromagnetic environment. Numerical and experimental results are compared for a sample of coaxial cable.
