Normalized reflection spectra of a surface coupled nanoparticle array with longitudinal spacing under two conditions: (dashed line), and (solid line). Inset: Schematic of the fabricated sample structure.
Geometry dependent reflection spectra of surface-coupled metal nanoparticle arrays as a function of longitudinal particle spacing . The color scale represents normalized reflectivity. Symbols mark the positions of reflection minima. The lateral nanoparticle resonance wavelength is indicated by the dashed line.
Calculated SP dispersion relation of the air- system. Experimentally observed reflection minima of the nanoparticle arrays are included as a function of (open symbols) and (filled symbols). The corresponding modes are indicated schematically. The lateral nanoparticle resonance frequency is indicated by the dashed line.
