Square Split Ring Resonators: Modelling of resonant frequency and polarizability

Abstract

In this paper, we propose a theoretical model to estimate the resonance frequency and the magnetic polarizability of the square split ring resonators (S-SRR) having varying gap width within the rings. The model also predicts the quantitative change in polarizability depending on the geometrical orientation of the S-SRR. The computed results are verified with results obtained using an electromagnetic simulator.
