Fano-Like Resonance in Cylinders Including Nonlocal Effects

We investigate the optical response of a metallic wire calculated from the classical electromagnetic theory. The Drude (local) approach is compared with the semi-classical hydrodynamical theory calculations that reveal the Fano-like resonances of subsidiary peaks originated from the nonlocality. The bulk plasma resonances containing the nonlocal effects could be depressed by increasing the dissipation, while the blue shift of the surface localized plasma resonances could be enhanced by increasing the Fermi velocity.
