The experiment device choose strong electromagnetic field simulation and environment protection technology defense science, technology and key laboratory auspicious tile level ultra-wideband electromagnetic pulse radiation system, its Gaussian pulse signal in a single week, time domain and frequency domain expression were [4]
Common mode current amplitude with the increase of the field radiation (irradiation distance of the reduction of) and increase, this and the results of consistent trend; And differential mode voltage in the simulation calculation, as the control of the wire materials, line diameter, the length of the same sex, and in close by spacing is small, so the calculation results of 0 V.
