TLDR
In this article, a new modeling technique for plasmon-based metallic nanoparticles under the influence of an electromagnetic field is presented, which approximates the coefficients of the admittance rational function.Abstract:
In this paper, we present a new modeling technique for plasmon-based metallic nanoparticles under the influence of an electromagnetic field. The model approximates the coefficients of the admittance rational function. The proposed model utilizes spherical wave functions to describe the field and it provides an equivalent ladder-form RLC realization. Simulation results show that our model matches very closely with the exact solution. Our newly developed model can be used as a basic building block to develop an equivalent circuit model for metallic nanoparticle-based plasmonic waveguidesread more
