In this paper, a numerical procedure for computing electromagnetic fields in a three-dimensional space using the constrained interpolation profile (CIP) method is presented. Then, this method is applied to computing electromagnetic fields, which are generated by an engineering lightning return-stroke model such as the transmission-line (TL) model, the modified TL model with exponential current decay (MTLE) or the traveling-current-source (TCS) model located on flat perfectly conducting ground, and the CIP-computed electric- and magnetic-field waveforms are compared with the corresponding waveforms computed theoretically and using the finite-difference time-domain (FDTD) method.
