Research On the LEMP Environment Simulator

摘要

For the purpose of studying the protective reinforcement technology and electromagnetic damage mechanism of the electronic equipment induced by LEMP field, on the foundation oj theoretical calculation of LEMP radiation field, the lightning electromagnetic environment simulator has been designed using impulse voltage generator and GTEM Cell. It can produce and transport the lightning electromagnetic wave that the peak strength of electric field is high about 400 kV/m. It is conveniently to change the rise time and half-width time of the LEMP by changing the wave-front resistance and wave-tail resistance, so that the simulator can simulate different kinds of LEMP waves.
