摘要：
The paper presents the mathematical basis of electromagnetic field modeling above lossy ground and the obtained results of the propagation electromagnetic field analysis. A model of cylindrical wave propagating around a lightning return-stroke channel is used during computer calculations, and as a lightning return-stroke current the model called as MTLE. The channel-base current is approximated function proposed by Nucci. Finally, a compression between obtained results for selected geometrical parameters of lightning channel and for different distances from the striking point is presented.
