Overview of Surface-Volume-Surface Electric Field Integral Equation Formulations for 3-D Composite Metal-Dielectric Objects

The Surface-Volume-Surface Electric Field Integral Equation (SVS-EFIE) has been recently generalized to solution of general scattering and radiation problems for 3D composite objects. These objects can be formed by multiple piece-wise homogeneous dielectric regions which do or do not share common boundaries. Generalization to the composite objects formed by metal and piece-wise homogeneous dielectric regions which share common boundaries has also been demonstrated. Since the SVS-EFIE formulation utilizes only the electric field dyadic Green’ s functions, it can be extended to the case of composite objects situated in non-magnetic planar multilayered media by casting its operators into the mixed-potential form using classical Michalski-Zheng’ s approach. Examples of the above SVS-EFIE formulations are summarized in the paper.
