Scattering of electromagnetic waves at the corrugated interface between index-matched media

Mostrar todas las versiones(2)

We consider the scattering of s-and p-polarized electromagnetic waves incident onto the periodically corrugated boundary between index-matched media. First we find the eigenmodes supported by this kind of interface by means of a perturbative solution to the corresponding homogeneous problem and show...
