摘要

In this paper, a numerical procedure for computing electric and magnetic fields in a three-dimensional space using the constrained interpolation profile (CIP) method is presented. Then, this method is applied to computing electric and magnetic fields, which are generated by a current wave propagating upward along a vertical lightning return-stroke channel. The lightning return-stroke channel is modeled by a phased-current-source array. The spatial and temporal distribution of the lightning return-stroke channel or phase-current-source array is represented by a new simple mathematical function of height, time and channel-base current.
