Time domain modeling of electromagnetic field coupling to transmission lines

Transient behaviour of a finite length horizontal wire above a perfectly conducting ground, illuminated by an electromagnetic pulse, is analyzed in the time domain. A mathematical model is based on the thin wire approximation and the corresponding time domain Hallen integral equation. The integral equation is solved by the space-time finite element procedure providing accurate and stable results. The numerical results for the current distribution along the unloaded and loaded wires are presented in the paper.
