A method for determining the surface roughness parameters of metal film with surface plasmon spectroscopy is proposed.

The results obtained from multiple scattering method show that the periodic dielectric spheres on the upper surface of the metal could induce surface plasmons on the metal-dielectric interface.

These nanoparticles exhibit plasmon resonance which enhance the non-linear optical properties of glass, so that implanted glass may play an important role for production of all-optical sw...
