In this work the effects of lightning path tortuosity is investigated by regarding the discharge channel as a fractal antenna whose associated EM field can be evaluated by superimposing the “exact"” contribution of the single line radiators composing the whole channel. The relationship between the fractal dimension of the discharge channel and the fractal dimension of the generated time domain EM fields is considered. The influence played on such a relationship by the distance between EM source and observation point is also studied by analysing the fields evaluated at far and close distances

Abstract
In this work the effects of lightning path tortuosity is investigated by regarding the discharge channel as a fractal antenna whose associated EM field can be evaluated by superimposing the “exact"” contribution of the single line radiators composing the whole channel. The relationship between the fractal dimension of the discharge channel and the fractal dimension of the generated time domain EM fields is considered. The influence played on such a relationship by the distance between EM source and observation point is also studied by analysing the fields evaluated at far and close distancesI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
