Abstract:Plasmonic Fano resonances have recently attracted a great deal of research interest due to their sharp asymmetric profile, high sensitivity to the ambient material and low radiation damping. In this paper, we extend the plasmonic Fano resonances that resulted from the interference between bright and dark modes in a coreshell nanoparticle system for novel biosensing, optical switching applications, by using the theory of transformation optics. To this end, we consider the optical properties of dielectric-core-m… Show more
