Plasmonic excitations in metallic nanoparticles: Resonances, dispersion characteristics and near-field patterns

Metamaterials acquire their functionality from the structuring of the small building blocks, 'meta-atoms', which were often approximated as small LCR circuits. This paper provided a first detailed study of the plasmonic nature of LCR resonances for nanoparticles of a variety of shapes. This paper won a SAOT Student Award 2010 (Erlangen University), as the most innovative paper of the year, has led to a €5m funding (Excellence Cluster Engineering Advanced Materials) by the German Research Council (DFG) and has been used in further research on L-shaped nanoparticles (Tampere U), LT-shaped nanohole arrays (Fuyang U) and faced-folded nanorods (Seoul U).
