Modeling the Interaction of Light with Plasmonic Nanoparticles
Plasmonic nanoparticles have received increased interest due to their numerous potential applications in the field of optics and optoelectronics. Currently such metallic nanoparticles are applied in semiconductor devices, such as light emitting diodes (LEDs) and solar cells. The optical behaviour of a single plasmonic nanoparticle is can be easily described with several analytic or semianalytic methods (e.g. quasistatic approximation, Mie-theory). However for modeling the interaction of a nanoparticle dimer with polarized light we have to use numerical simulations. In this work we model the scattered electromagnetic field of a silver nanoparticle dimer interacting with light with different polarization. For these simulations we used COMSOL Multiphysics® software and the RF Module.
