Effects of return stroke parameters and soil water content on EMF characteristics

Electromagnetic pulses produced by lightning return strokes travel long distances both aboveground and underground. This study investigated the effects of return stroke parameters on electromagnetic propagation over lossy ground. The lightning return stroke channel was modeled using the Modified Tra...
