Surface-Electromagnetic-Wave-Enhanced Raman Scattering by Overlayers on Metals

Abstract

Using a general formulation we show that by using surface electromagnetic waves in an attenuated-total-reflection prism configuration it should be possible to enhance the intensity of Raman scattering by a thin overlayer on a Ag surface by two orders of magnitude and that the use of surface electromagnetic waves may in fact make it possible to observe coherent anti-Stokes Raman scattering by the overlayer.
