Polarization properties of single metallic nano-spheroid using 3-D boundary element method
چکیده انگلیسی

The polarization properties of an individual metallic nano-spheroid illuminated by the linearly polarized light are studied based on 3-D boundary element method. The scattering cross sections and the local field enhancements are investigated in detail when the incident lights are with different polarization directions and wavelengths. The numerical results show that the polarization direction of the incident light can strongly influence the scattering spectrum and the enhanced field distribution of the metallic nano-spheroid. The incident light with polarization direction parallel or perpendicular to the major axis can inspire longitudinal or transversal local surface plasmons resonance modes, respectively. The electric field enhancement and distribution around the nano-spheroid can be conveniently tuned by carefully selecting the polarization direction and wavelength of the incident light.
