We make a theoretical investigation of nonlinear surface polaritons localized at a single interface separating a nonlinear conventional dielectric medium and a linear indefinite medium. The propagation properties of such nonlinear surface polaritons are demonstrated in several distinct frequency intervals. The surface effect of optical beams suffers different dynamics from the propagation (transmission) effect in indefinite media. The existence conditions, frequency thresholds, group velocity, and the power fluxes of the nonlinear surface polaritons are also discussed in detail.
