    "abstract": "We discuss the effect of the local field polarization in metallic\nnanostructures where large field enhancements can be induced by excitation of\nlocalized surface plasmons. To demonstrate the importance of these effects, we\nstudy a few model systems in 2D and 3D. As an experimental probe of this\neffect, we suggest to use depolarization ratios in Surface Enhanced Raman\nSpectroscopy (SERS) measurements. We attempt to relate the polarization of the\nlocal field to the depolarization ratios in SERS conditions. This approach\ncould also lead to some better understanding of the SERS mechanisms at a\nmicroscopic level.",
