Electromagnetic models based on antenna theory have been recently applied in lightning studies. Their practical use is facilitated by existing thin-wire antenna numerical codes that utilize localized voltage sources. Such voltage sources have to be tuned to provide the lightning channel-base current for which experimental data are available. This involves some preparatory steps, such as the determination of the input impedance of the antenna (in the frequency domain) and Fourier and inverse… CONTINUE READING
