Abstract
Electromagnetic topology based simulations have been carried out to characterize the response of a semishielded multiconductor line to external electromagnetic pulses. The concept of transfer function generation through an aperture for this simulation technique is explained and a methodology to apply the concept to a multiconductor transmission line is proposed. Using this simulation approach the effects of conductor length, its distance from the aperture, and the response of the cable at various frequencies have been studied. The results compare well with experiments. The length of individual cables, its terminating impedances, and the distance of the individual cable from the aperture influences the behavior of the cables under external threat. Analysis shows that the effects from an external electromagnetic pulse are more severe than from lightning.
