Abstract

A special interest in Plasmon mode resonance in toroidal nano-particles where a full and comprehensive analytical investigation is presented for different toroidal nano-structure within the quasi-static approximation. Then the optical response of gold nanorings and the associated near-field mapping when exposed to a broadband electromagnetic wave were obtained by the implementation of numerical methods to solve for the transient response. The numerical and analytical investigation lead to the design of an optical nano-trapping system and the identification of strong coupling interaction between toroidal plasmons and J-aggregate dye molecules a promising component in the design of novel optoelectronic material.
