Electromagnetic susceptibility analysis of open-wire systems

The susceptibility of an open-wire system, used to control operational devices, to electromagnetic disturbances is analyzed with the aid of Lorentz's reciprocity theorem. Voltages in the terminations of the system induced by a transient disturbance, e.g. lightning, are determined and numerical results are presented. The system is modeled as a transmission line system consisting of conducting wires over a perfect conducting plane.
