Abstract

Surface-enhanced Raman spectroscopy is a promising method for analysis of gas media composition. In this work we present an analysis of resonant metal-dielectric holographic gratings providing an essential local field enhancement due to excitation of the surface plasmon-polaritons. It is shown that structure parameters yielding an optimum far-field resonance excitation are not necessarily correspond to optimum local field maximum.
