摘要：

An analytical technique for correlating ground level return-stroke currents to the produced surface electromagnetic fields is discussed. The ground is realistically assumed with finite conductivity. The lossless nonuniform transmission line model with exponentially decreasing cross section upwards, turns out to be a powerful, as well as plausible, discharge channel representation. By virtue of the analytical fashion of this approach, a number of details typically ascribed to the electromagnetic performances of a lightning appear on the whole suitably accounted for. Therefore, the employed work hypotheses and the results found by this investigation a priori performed for EMC studies, can be assumed as useful remarks for a better outline of the discharge phenomenon.
