Modeling EM Coupling onto Vehicle Wiring Based on the Combination of a Hybrid FV/FDTD Method and a Cable Network Method

A numerical hybrid technique combining finite volumes and finite differences in time domain is used to calculate the incident field generated at cable ends inside a car illuminated by a nearby antenna. The incident fields are then used as source terms for a transmission line model in order to calculate the wiring response. These results are compared with corresponding measurements carried out in a large semi- anechoic chamber. The efficiency of applying the field-to-transmission-line technique with a hybrid model is discussed.
