Abstract

A kind of electric and magnetic field generators with adjustable waveforms and intensity output to simulate lightning electromagnetic fields are presented. The electric fields measured by a dipole antenna and ranged from 0 to 300kV/m can be generated within the GTEM cell by feed-in of an impulse voltage. The magnetic fields measured by a `B-dot´ coil and ranged from 0 to 3000 A/m can be generated within the coil by feed-in of a surge from the lightning surge generator. The relatively homogeneous lightning electromagnetic pulse (LEMP) environment could be provided within certain area in the GTEM cell and the coil, which can be used to evaluate the immunity of small electronic systems or devices towards LEMP with low cost.
