dc.description.abstractIn this work, a numerical method is developed to solve a forward-scattering problem of three-dimensional (3-D) objects buried into two half-space media with two-dimensional (2-D) locally rough interface. The proposed method exploits the electric field integral equation (EFIE) formulation of the scattered field which involves the dyadic Green's function of the background medium. Since the required Green's function has no analytical expression (in general), buried object approach (BOA) is applied to calculate it numerically. Method of moments (MoM) is then used to solve the EFIE. The presented method is numerically validated by comparing it with finite difference time-domain (FDTD) method. Furthermore, an elaborative numerical analysis of the proposed method is presented to show its feasibility for various roughness profiles and buried objects.
