3-D scattering from a PEC target buried beneath a dielectric rough surface using a hybrid formulation and a fast solver

Résumé

In this paper, an efficient hybrid KA-EFIE formulation is deployed to analyse the ElectroMagnetic (EM) scattering from a three-dimensional (3-D) Perfectly Electric Conducting (PEC) object buried beneath a two-dimensional (2-D) dielectric rough surface. In this approach, the electric and magnetic current densities on the rough surface are analytically obtained through the current-based Kirchhoff Approximation (KA) [1] whereas the electric current density on the buried object is rigorously determined by solving the Electric Field Integral Equation (EFIE) using the Galerkin’s Method of Moments (MoM) with Rao-Wilton-Glisson (RWG) basis functions. The KA-EFIE matrix equation is then efficiently solved by the iterative PILE (Propagation-Inside-Layer-Expansion) method [2] combined with the algebraic Adaptive Cross Approximation (ACA) [3]. The current densities on the dielectric rough surface are thereafter used to handle the bistatic Normalized Radar Cross Section (NRCS) patterns.
