Equivalent Circuit Model for Double Split Ring Resonators

This article focuses on the electric modeling of split ring resonators with a new approach based on an equivalent circuit. The elements of circuit are determined from geometric parameters forming the three dimensional model of this type of resonators. In the first part, an analytic study is proposed about the determination of the components of the circuit according to a function of physical parameters and a review about comparison between obtained results when the simulation of two different models is presented. I n the second part, a study is devoted to demonstrate the rate influence, according to the variation of relative permittivity and the variation of physical parameters, are the frequency characteristics of our electric equivalent model. The results of simulations are demonstrated with using the two commercials software HFSS and ADS.
