Abstract
Surface magnetoplasmons on a single semiconductor–dielectric interface in a transverse static magnetic flux have been modelled. The dispersion diagrams exhibit nonreciprocal behaviour for the forward and reverse propagation as expected, but the effect of the permittivity of the dielectric is shown for the first time. The elliptical polarization of the electric field in both media, near the interface, above and below the EWR frequency, for both directions of propagation is computed. The results have implications for the development of miniature isolators and phase shifters at millimetric and submillimetric wavelengths. © 2004 Wiley Periodicals, Inc.
