Query: Plasmon-mediated Polarization Anomalies in Surface Enhanced Raman
  Scattering (SERS)   We discuss the effect of the local field polarization in metallic
nanostructures where large field enhancements can be induced by excitation of
localized surface plasmons. To demonstrate the importance of these effects, we
study a few model systems in 2D and 3D. As an experimental probe of this
effect, we suggest to use depolarization ratios in Surface Enhanced Raman
Spectroscopy (SERS) measurements. We attempt to relate the polarization of the
local field to the depolarization ratios in SERS conditions. This approach
could also lead to some better understanding of the SERS mechanisms at a
microscopic level.
