General formulation for light scattering by a dielectric body near a perfectly conducting surface

We present an efficient approach for calculating the electromagnetic scattered fields (light) from a single dielectric body situated above a perfectly conducting (or reflecting) half-space. This approach employs the boundary integral equation method and is applicable to arbitrarily shaped scatterers located anywhere above the conducting half-space surface, impinged upon by arbitrary incident fields. Numerical results for spherical scatterers are presented and are compared with published results obtained with an analytical approach.
