Paper Abstract

We study the scattering of electromagnetic waves at lossy metallic rough surfaces with bivalued cavities. In this particular kind of scatterer two resonant mechanism of very different nature can manifest themselves to produce highly selective reflectivity responses: i) surface plasmons and ii) resonant microcavities. To separate the contributions from each resonant mechanism, we compare the results obtained for two different problems: the diffraction problem for infinitely periodic grating with cavity like grooves and the homogeneous problem for a plane surface with a single cavity.
