Long-wave approximation for hybridization modeling of local surface plasmonic resonance in nanoshells

Opt Lett. 2011 Jan 15;36(2):247-9. doi: 10.1364/OL.36.000247.

Abstract

A hybridization model for the localized surface plasmon resonance of a nanoshell is developed within the framework of long-wave approximation. Compared with the existing hybridization model derived from the hydrodynamic simulation of free electron gas, this approach is much simpler and gives identical results for a concentric nanoshell. Also, with this approach, the limitations associated with the original hybridization model are succinctly stated. Extension of this approach to hybridization modeling of more complicated structures such as multiplayered nanoshells is straightforward.
