Local field enhancement of nano-structured metallic target irradiated by polarized laser beam

M. Nikbakht, M. H. Mahdieh

Abstract

The local field enhancement is studied numerically in samples of metallic nanoparticles (NPs) randomly distributed over a metallic substrate. The sample was assumed to be irradiated by polarized laser beam. Based on dipole-dipole approximation (DDA), the electric field was calculated Two-dimensionally at the irradiated region. The results show that the optimized field enhancement is strongly depends on NPs characteristics, beam polarization and incident angle.
