A simple procedure to express the lightning base current in the frequency domain is presented. The formula, based on a piecewise approximation of the lightning base current in time domain, allows obtaining an expression in the frequency domain in terms of elementary functions. The presented procedure is fast and general, since it can be used with any current waveshape.

Abstract
A simple procedure to express the lightning base current in the frequency domain is presented. The formula, based on a piecewise approximation of the lightning base current in time domain, allows obtaining an expression in the frequency domain in terms of elementary functions. The presented procedure is fast and general, since it can be used with any current waveshape.File in questo prodotto:
