The dispersion characteristics of surface wave propagated on a deeply corrugated metal surface are analyzed. Surface wave becomes slow wave, because surface wave is evanescent wave to the direction away from the corrugated metal surface. The surface wave is possible to be backward wave, due to the periodic nature of the corrugation of metal surface. Because the Rayleigh hypothesis has failed for the analysis of an electromagnetic field upon a deeply corrugated surface, the dispersion relations are solved by a direct numerical computation of wave equations.
