Surface Waves at the boundary of a magneto-active plasma

Dispersion relations are obtained for surface waves propagating along plasma—vacuum and plasma—plasma interfaces in a direction perpendicular to a uniform magneto-static field (that lying parallel to the interface), by setting to zero reflexion coefficient for an incident plane wave. Complete solutions to the dispersion relations are presented for both cases and the results are displayed diagrammatically. Comparisons are made with the work of other authors.
