Surface plasmon resonances effects on various geometries of solid-silver and silver-shell nanocylindrical pairs that interact with incident plane wave of transverse magnetic polarization are simulated by using the finite element method. Results show that the silver-shell nanocylindrical pair exhibits tunable plasmon resonances in the near-field zone that are not observed for the solid-silver case of similar size. It is also found that the facing corners of nanocylindrical pairs induce more surface plasmons in a wider range of wavelength. © 2010 VSP.
