Abstract:

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 permeability. The chiral is also specified by its chiral parameter. As a result it is found that surface wave excitation is theoretically possible. The range of values of the chiral parameter in which surface waves can be excited is very narrow and depends on the constants of both media. The condition that at least one of the media must be dissipative seems to be necessary to have excitation. To obtain these results, the dispersion relation of the interface is deduced. Chiral media are described by the Drude–Born–Fedorov constitutive equations. The exact dependence of the fields on the chiral parameter is kept in the computation. © 1996 Taylor & Francis Group, LLC.
