Propagation of surface plasmons along an arbitrary smooth interface between two media is studied asymptotically in the short-wavelength limit. The leading order term of the electromagnetic field of a surface plasmon differs only by a factor  from its EM field in the case of a planar interface. Results enable one to control the enhancement of the surface plasmon field  and its spatial localization by altering the interface geometry.
