Abstract
Coupling of free electrons with electromagnetic fields near but below the plasma frequency of confined metallic nanostructures leads to plasmonic resonances. Their spectral response is strongly dependent on the geometry, i.e., for nanorods, changes in the aspect ratio of the cross-section to the length shift the resonance frequency. In this way, plasmonic resonances can be tuned from blue to infrared, but not actively.
