Abstract

Localized surface plasmon resonances (LSPRs) in metallic nanoparticles (NPs) are calculated by a boundary integral equation (BIE) method. The response to the incident electromagnetic field and the NP polarizability are shown to depend on eigenvalues and eigenfunctions of the integral operator associated with BIE. The NP polarizability is conveniently expressed as an eigenmode sum of analytic terms when the Drude model of metals is used. The proposed polarizability decomposition is proven to offer an analytical tool for the design of plasmonic nanostructures.
