Abstract

We apply the plasmon hybridization (PH) method to a general metallic nanowire/double-shell structure, providing a simple and intuitive description of the plasmon excitations of the system. In special cases, we find explicit forms of surface plasmon oscillations, in terms of interaction between the bare plasmon modes of the individual surfaces of the coated metallic core. In particular, we show that when the longitudinal wave vector is zero (q=0), the PH of core/double-nanotubes has a behavior similar to coated metallic nanospheres. We present numerical results displaying how the plasmon excitations of the system depend on the dielectric difference between the metallic core and metallic shell.
