Hybridization of Singular Plasmons via Transformation Optics

Sanghyeon Yu, Habib Ammari

Published 2018-07-24Version 1

Strongly interacting metallic nanoparticles are useful for controlling light at the nanoscale due to their surface plasmons. Here we develop a new physical model for understanding plasmons of interacting particles. We combine both the hybridization model and transformation optics so that our model gives a simple and intuitive picture when the particles are close-to-touching. In the proposed approach, the system's plasmon is a combination of the gap-plasmons of each pair of particles. This provides new physical insights into how the spectrum of the plasmons depends on global and local features of the geometry.
