Numerical simulations are used to study the near-field properties of nanocylinders. Specific attention is given to surface-plasmon-polariton resonances and field localization in dielectric cylinders with partial metal coating. Conditions for observing local-field enhancement are investigated as well as the degrees of freedom that are available to customize the wavelength response of the nanosystem.
