Abstract
This paper describes the construction of a radio frequency electromagnetic environment model under strong electromagnetic pulse radiation,based on the finite element multi physics field simulation software COMSOL5.6,in order to obtain the distribution of radio frequency electromagnetic fields in space.It calculates the distribution of strong electromagnetic pulse spatial electromagnetic fields at different distances,and simulates the equivalent sources generated by the first and second harmonics of strong electromagnetic pulses.
