Abstract
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.
Highlights
The analysis of scattering properties of the perfectly conducting (PEC) objects buried in a lossy half-space has been of continuous interest in the various areas of application, such as ground penetrating radar (GPR) systems and related applications in civil engineering [1], as well as design and modeling of lightning protection systems (LPS) [2, 3]
The transient current induced along the wire scatterer, featuring a thin wire approximation, can be obtained using direct approach related to modeling of the electromagnetic (EM) wave coupling to a thin wire structure directly in time domain, providing better physical insight, accurate modeling of highly resonant structures, and easier implementation of nonlinearities [10]
Among the huge diversity of statistical approaches available in the literature, the purpose of this paper is to focus on spectral stochastic techniques [6]
Summary
The analysis of scattering properties of the perfectly conducting (PEC) objects buried in a lossy half-space has been of continuous interest in the various areas of application, such as ground penetrating radar (GPR) systems and related applications in civil engineering [1], as well as design and modeling of lightning protection systems (LPS) [2, 3]. The transient current induced along the wire scatterer, featuring a thin wire approximation, can be obtained using direct approach related to modeling of the electromagnetic (EM) wave coupling to a thin wire structure directly in time domain, providing better physical insight, accurate modeling of highly resonant structures, and easier implementation of nonlinearities [10]. This current is governed by integrodifferential equation of Pocklington type. Analytical solution can be used within hybrid approaches for modeling complex structures, wherein computational time can be significantly reduced [9]
