Modelling of lightning using fractals

In this paper, basic principles of fractals and their application for analysing EM radiation from lightning discharges in the atmosphere are discussed. Attention is drawn to how fractals have been used for geometric modelling of lightning to take care of tortuosity and branching. EM radiation can be computed from these models to obtain time and frequency domain information, which can be useful in estimating interference levels and setting up EMC standards.
