Abstract
We explore the plasmonic interactions among multiple localized plasmon modes in isolated dimers as well as in their periodic arrays by means of quasi-analytical models. A model based on dipolar approximation was developed for that purpose and extended to periodic array of particles using coupled dipole approximation technique. In order to capture the modes coupling at shorter distances, with the use of the plasmon hybridization theory, we applied its formalism to dimer structures and studied the plasmonic resonances as a function of particle mutual distance. All models predictions are compared with rigorously computed data.
