Paper Abstract

Scattering resonances of metal nano-strip resonators are described as a consequence of formation of standing waves due to counter-propagating short-range (and slow) surface plasmon polaritons and gap plasmon polaritons, which are electromagnetic waves bound to and propagating along a nanometer-thin metal film, and a nanometer-sized gap between metal surfaces, respectively. Scattering spectra and resonant fields are presented for single-metal-nano-strip resonators and gap plasmon resonators with two closely spaced metal nano-strips. It is shown how strip resonators can be designed for any resonance wavelength in the range from 600nm to 1600nm.
