Abstract

Lightning, not only on the ground of buildings and electronic equipments but also for the aerospace, defense and military fields, equipment, facilities, has a great threat. In view of this situation, the deduced lightning electromagnetic field calculated expressions at any point in space is of great significance. Based on the assumption that the earth is a perfect conductor of the situation, and started from the Maxwell equations for the spatial distribution of lightning electromagnetic field calculation and analysis, we derived the electromagnetic field around the lightning channel by the lightning current expression. This expression reflects the lightning speed of the electromagnetic field and the lightning current comeback, lightning current size and field point height relationships between multiple factors. Finally, with the Matlab numerical simulation to get the electromagnetic field distribution space near the ground lightning, we would see it is coincide to the actual variation of lightning electromagnetic field and verified the feasibility of the model. Therefore, this method would provide a new theoretical basis for further study of lightning electromagnetic field.
