Propagation and excitation of eigenmodes at isotropic-gyroelectromagnetic index-matched interfaces

We study the relation between the excitation of eigenmodes at isotropic-gyroelectromagnetic flat interfaces under index-matching condition and the singular behaviour of the reflectivity at grazing incidences. We show that, as in the isotropic case, these eigenmodes can be excited by waves at other a...
