Description
The four wavenumbers associated with planewave propagation in a Faraday chiral medium (FCM) with relatively huge magnetoelectric coupling give rise to enhanced possibilities for negative-phase-velocity propagation and therefore negative refraction. They can also give rise to the phenomenon of negative reflection. In particular, for a nondissipative example, we deduced that an incident plane wave with positive/negative phase velocity can result in a negatively reflected plane wave with negative/positive phase velocity, as well as a positively reflected plane wave with positive/negative phase velocity.
