A Stochastic Analysis of the Transient Current Induced along the Thin Wire Scatterer Buried in a Lossy Medium

Abstract EN

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 either by a plane wave transmitted through the air-ground interface or by an equivalent current source representing direct lightning strike pulse.

Transient current induced at the center of the wire, governed by corresponding Pocklington integrodifferential equation, is determined analytically.

This antenna configuration suffers from uncertainties in various parameters, such as ground properties, wire dimensions, and position.

The statistical processing of the results yields additional information, thus enabling more accurate and efficient analysis of buried wire configurations.
