Abstract: The nonlocality (spatial dispersion) is a barrier to a good understanding of atomic scale response to light and becomes much important for the nano-structures. In this talk, we shall derive the equivalent permittivity and permeability for metallic nanowires with spatial dispersion are derived analytically. Numerical results show a good agreement between the local full-wave theory with our equivalent permittivity and permeability (EP) and the conventional nonlocal full-wave theory. When the electromagnetic wave is incident on the nonlocal nanocylinder, multiple Fano resonances take place due to the coupling of the excited dipole longitudinal modes, and the nonlocal nanocylinder can be designed to abruptly realize the transition between full transparency and strong scattering. To one's interest, both positions of transparency and strong scattering can be well described by our equivalent local permittivity. Our study may be helpful in the design of optical nanoswitches and nanomemories.
