Abstract: We present a simple and intuitive picture, an electromagnetic analog of molecular orbital theory, that describes the plasmon response of complex nanostructures of arbitrary shape. Our model can be understood as the interaction or "hybridization" of elementary plasmons supported by nanostructures of elementary geometries. As an example, the approach is applied to the important case of a four-layer concentric nanoshell, where the hybridization of the plasmons of the inner and outer nanoshells determines the resonant frequencies of the multilayer nanostructure.

Color-switched directional ultracompact optical nanoantennas
TL;DR: In this paper, a novel optical nano-antenna composed of three gold nanodisks ultracompactly arranged in the end-fire configuration was proposed, and it was found that the emission of a local light source can be remarkably directed and switched based on its color between two opposite directions.

Excitation of Multiple Fano Resonances in Plasmonic Clusters with D2h Point Group Symmetry
TL;DR: In this article, a general understanding of Fano resonances in clusters with D2h symmetry was provided, and it was shown that the excitation of B3u and B2u dark sub-radiant modes contributes to the appearance of four kinds of resonances for hexamers with D 2h symmetry.
