Planar interface between a chiral medium and a metal: Surface wave excitation

The feasibility of excitation of surface waves at a single planar interface is demonstrated numerically. The interface separates a chiral medium from an isotropic and achiral medium; this latter could be a metal. Both media are characterized by their dielectric permittivity and their magnetic permea...
