Analytic LC model for plasmonic resonances in nano-structured split-ring resonators

ORAL

Abstract

We systematically investigate the plasmonic resonant behavior of metallic nano-structured split-ring resonators as a function of the size of the split gap, substrate permittivity, metal skin depth, and sample height. We performed simulations of the structures and examine the E-field and current density maps. We present a simple, analytic LC model to describe the lowest order resonance and its dependence on the aforementioned parameters.
