On the transmission line model for lightning return stroke representation (original) (raw)

The paper explores the transmission-line model (TL model) for representing lightning return strokes, highlighting its application in lightning electromagnetic pulse (LEMP) calculations, particularly in relation to power and communication lines. It contrasts idealized conditions of a vertical perfectly conducting channel with practical scenarios involving non-zero-radius conductors and realistic current sources, focusing on the differing electromagnetic field structures produced. The research emphasizes the limitations of traditional TL models under more realistic constraints, advocating for caution when using these models to study lightning physical processes.
