Stochastic collocation analysis of the transient current induced along the wire buried in a lossy medium

The paper deals with the stochastic collocation analysis of a time domain response of a straight thin wire scatterer buried in a lossy half-space. The wire is excited by a plane wave transmitted through the air-ground interface. Transient current induced at the center of the wire, governed by corresponding Pocklington integro-differential equation is determined. This configuration, as is the case with many electromagnetic compatibility (EMC) issues, suffers from uncertainties in various parameters, such as ground properties, wire dimensions, position, etc. The obtained results yield additional statistical information thus enabling more accurate and efficient analysis of buried wire configurations.
