The effect of shifting on wires and split ring resonators

Abstract

Based on finite integration technique, the effect of shifting introduced in wires and split ring resonators on the pass band and resonant frequency of wires and split ring resonators is investigated. We similar pass bands and resonant frequency for two shifting structures of negative refractive index materials.The results show that there exists a shifting for resonant frequency and a narrowing in pass band deduced by the introduction of shifting wires and SRRs into materials.
