The Smith–Purcell radiation from a charge moving across a penetrable grating is studied. We account for the finite permittivity and the absorption effect of the grating and find that enhancement of the radiation will occur near particular angles of observation at which the phase-matching condition for the excitation of the surface-plasmon mode is satisfied.
