摘要

Modern vehicles contain many sensitive electronic devices whose operation may be affected by electromagnetic pulses appearing in the car body. A car can be considered as a hollow metallic structure with partitions enclosing dielectric objects that represent human bodies and other dielectric inclusions. This system behaves as a resonator for incident EM waves and pulses. It is important to investigate the electrodynamic resonant behaviour of such a complex system to understand, predict and avoid any potential harmful influence of EM pulses on sensitive devices inside the car. Experimental measurements are expensive, and most of the numerical methods are time consuming and require significant computer resources making those investigations impractical or very slow. The method of auxiliary sources (MAS) has been implemented as a fast powerful method for simulation of diffraction processes to solve the stated problems. The computations show that this method is efficient and can be applied for real-time investigations.
