• A modification of the Antenna Theory (AT) model of lightning return stroke channel is proposed to realistically represent its nonlinear behaviour. In this model, the constant channel distributed resistive loads are replaced by an appropriate set of non-linear resistors. The model is used to compute current distribution along the channel and the resultant electromagnetic field in various distances. It is shown that the modified model can accurately predict those features in measurement data which are not seen in the conventional theoretical results.
