Abstract

In IEC62305, GB50057—2010 and MIL—STD—464 double exponential current waveform has been defined as standard base-current waveform, it is noteworthy to develop a solution for the electromagnetic fields which utilizes this waveform. In order to facilitate the integration required for deriving the field, Taylor series expansion will be used for all variable dependent exponential terms within the current waveform. This methodology greatly simplifies the integration required to solve for the electromagnetic fields in an approximated closed form. However, by utilizing Taylor series to approximate the variable dependent exponentials, the electromagnetic fields' accuracy becomes a function of the number of terms used. Consequently, a correction factor will have to be added in order to reshape the electromagnetic fields which results from the modified base-current waveform.
