Abstract

In this paper, we present a new modeling technique for plasmon-based metal single nanoparticles under the influence of electromagnetic field. A model based on continued fractions is derived to approximate 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
