Abstract
Point source scattering by two rectangular dielectric obstacles on a perfectly conducting screen is studied by solving approximately the integral equations resulting from the scattering theorem. The configuration can be used as a model describing antenna radiation over the sea in the presence of two islands, one of which is much larger than the other. The approach is scalar and two-dimensional, while a linear system, produced via analytical integrations, is derived to evaluate the field inside the scatterers. The received power on the two islands is presented in several diagrams as function of the material and distance parameters to estimate the signal coverage across the two regions.
