摘要：

Surface plasmon effects excitation from the three-pair arrays of silver-shell nanocylinders are investigated numerically by using the finite-element method. Effects from different illumination wavelengths, interparticle distance, interpair distance, and the radii of air hole in nanocylinders are studied. Compared to the three-pair arrays of solid silver cylinder, the near-field optical response of the shell exhibits electric field enhancements and redshift which are found to be strongly influenced by tuning the radius of the air-hole in the nanocylinders.
