In this paper the scattering of surface waves in the presence of a single defect in the metal-vacuum interface is investigated. By modifying the previous methods we could explore more general forms of defect and get transmission, reflection and scattering coefficients of surface plasmon using both Rayleigh expansions and the exact numerical solution of integral equation. Providing a new defect, reflection coefficient of the structure greatly increased compared to conventional structures. The maximum reflectivity is achieved when the defect is narrow which is called plasmon mirror.
