Abstract
RCS issues lead to problems of hundreds of thousands of unknowns as soon as the target gets greater than the wavelength. For computational limiting reasons, details of the coating cannot thus be meshed, even if they play a key role like in metamaterial design. Equivalent boundary conditions or effective medium approximation are then necessary. In this paper we consider spheres with plasmonic coatings. Exact and approximated RCS computations are compared over a broad range of RF frequencies.
