Abstract

The author investigates the characteristics of magnetic resonance band gaps for split ring structures. Resonance band gap width is related to the discrepancy of resonance frequency at two different Bloch wavelength scales. Large band gaps are achieved by lowering the resonance frequency on one hand, and raising the dissimilarity between two respective resonant modes on the other. By increasing the internal fraction of ring area, large resonance band gaps are obtained. The band gap features alter as the plasmonic effect becomes significant, where the kinetic inductance outweighs the geometric one and the magnetic resonance attenuates.
