Tunable surface plasmon resonance (SPR) and dipole cavity plasmon modes of the
scattering cross section (SCS) spectra on the single solid-gold/gold-shell nanorod have
been numerically investigated by using the finite element method. Various effects, such as
the influence of SCS spectra under x-and y-polarizations on the surface of the single solid-
gold/gold-shell nanorod, are discussed in detail. With the single gold-shell nanorod, one can
independently tune the relative SCS spectrum width by controlling the rod length and rod …
