Electromagnetic scattering by multiple three-dimensional scatterers buried under one-dimensional multi-layered media

A general theory is presented for the electromagnetic scattering by multiple three-dimensional scatterers buried under one-dimensional multi-layered media. Closed-form formulations for the electric fields excited by an arbitrarily-oriented electric dipole under the layered media are investigated at first, from which electric field integral equations for the buried dielectric objects, conducting objects, and coupled electric field integral equations for multiple buried dielectric and conducting objects are then obtained.
