A MoM-based EM code was applied to model the electromagnetic fields coupled to a vehicle by nearby lightning return strokes. The return stroke model was applied to investigate the effect of the lightning induced electromagnetic fields on wire harness in automobile that generates high peak current electromagnetic pulse (EMP) and potential EMI/EMC concerns on electrical and electronics (E/E) components. Frequency content of the lightning induced current pulse on the wire cable harness was also analyzed by Fast Fourier Transform (FFT).
