The analysis of vehicles electromagnetic environment based on TLM method

Utilizing the TLM (transmission line method) method, this paper discussed the electromagnetic environment of vehicles under the condition of high electromagnetic pulse (EMP). The simulation results show that the amplitude of electromagnetic intensity of external is higher about an order than that of internal. While the nearer the stimulation, the greater the amplitude of electromagnetic intensity amplitude, that is the amplitude of upper part in the vehicles is bigger than that of the bottom. The amplitude of electromagnetic intensity is symmetrical following with the symmetrical of the position of electromagnetic pulse stimulation. The amplitude of electromagnetic intensity of the polarization direction and propagation direction perpendicular to the body is higher than that of parallel to the body.
