Abstract

Electromagnetic pulse could enter the electronic system through several coupling ways, and thus affect its working performance to varying degrees. Electronic equipment and system generally placed in the metal cavity, in order to achieve electromagnetic shielding. The current density of the shell surface is an important parameter to describe the coupling characteristic of the shell under strong electromagnetic pulse environment, so it is necessary to calculate and analyse the surface current response of the shell under electromagnetic pulse. The influence of different size, shape, boundary continuity, symmetry, propagation direction of pulse source and frequency spectrum of incident wave on the surface current of metal conductor was calculated by using electromagnetic simulation software. The results show that under the condition of plane wave incidence, the induced current at the centre on the surface of the metal shell increases and decreases with the change under different conditions, but the amount of change in the mass is truly small, what’s more, the surface current waveform is consistent with the pulse source. Based on the simulation regularity, it can also provide technical reference for maximum value estimation and measurement point selection of shell surface current.
