Abstract

The finite‐difference time‐domain (FDTD) method is used to study the electric fields coupling into a vehicle exposed to lightning electromagnetic pulse (LEMP) waves. From simulation results, it is found that the maximum shielding effectiveness of about 72.5% occurred inside the vehicle. The shielding effectiveness can be highly improved by including a good conducting material in the windshield and auto glass. Inside the vehicle, it is also found that there are various reflections around the vehicle's body due to the influence of the vehicle structure on the incident LEMP waves.
