Abstract
We study electromagnetic waves localized near a surface of a semi-infinite dielectric
medium covered by a layer of graphene in the presence of a strong external magnetic
field. We demonstrate that a novel type of hybrid TE-TM polarized surface plasmons can
propagate along the graphene layer. We analyze the effect of the Hall conductivity on the
polarization properties of these hybrid surface waves and suggest a possibility to tune the
graphene plasmons by the external magnetic field.
