A Simple Approach to Characterize a Buried Object Under the Ground

Abstract

This study provides an alternative and straightforward approach to determining buried dielectric objects underground by employing the method of auxiliary sources. In the direct scattering problem, the Brewster angle is determined, and then the electromagnetic properties of the ground are determined. Later, the scattered field above the ground due to the buried object is evaluated. The localization of the buried object is obtained by the continuity of the field components while solving the inverse problem. The numerical experiments are done, and outcomes of the numerical experiments are compared with a commercial full-wave computational electromagnetic software. The outcomes reveal less than 1% deviation between the proposed approach and the commercial tool.

A fundamental approach: E-polarized electromagnetic wave diffraction by two dimensional arbitrary-shaped objects with impedance boundary condition

“…There are several reasons that researchers focus on the topic such as developing faster converging numerical approaches [18][19][20], employing different boundary conditions [12], [21], and proposing new mathematical perspectives [22][23][24][25]. In [18], near-zero-index objects involved in electromagnetic problems are investigated through a novel surface integral equation formulation.…”
