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.

Effect of number density on optimal design of gold nanoshells for plasmonic photothermal therapy.
TL;DR: The comparison of gold nanoshells with different cores shows that hollow nanOShells exhibiting relatively low absorption efficiency are less harmful to the healthy tissue and, hence, are preferred over the strongly absorbing nanosells.

Magnetic wire: transverse magnetism in a one-dimensional plasmonic system.
TL;DR: In this paper, a coupled, cut-wire pair-based metasurface operating at the terahertz frequencies was demonstrated to transform an electric wire to a magnetic wire and vice-versa through asymmetry-induced polymorphic hybridization with potential applications in photonic/electrical integrated circuits.

Shaping the nonlinear near field.
TL;DR: This work uses a far field Fourier imaging method to switch the third-harmonic emission from a single point source to two spatially separated but coherent sources, as in Young's double-slit assembly, and envision applications as diverse as coherently feeding antenna arrays and optical spectroscopy of spatially extended electronic states.
