Apex-angle-dependent resonances in triangular split-ring resonators

Electromagnetic resonances in individual and coupled split-ring resonators

We study experimentally and numerically the electromagnetic resonances in split ring resonators ~SRRs!, around 1 GHz. For an individual SRR, we show that both electric and magnetic fields can induce resonances, the magnetic one being the strongest. The utilization of such resonant structures as efficient microwave filter is also demonstrated. The coupling between two or more SRRs can be quite c...

Tunable Superconducting Split Ring Resonators

Cavity formation in split ring resonators

We report that it is possible to obtain a cavity structure by the deformation of a unit cell of an split ring resonator (SRR) structure. We presented the Q-factor of the cavity resonance as 192 for an SRR-based single cavity. Subsequently, we brought two and three cavities together with an intercavity distance of two metamaterial unit cells and investigated the transmission spectrum of SRRbased...

Localised bending modes in split ring resonators

We present band diagrams for in-plane elastic waves propagating within a doubly periodic structure involving Split Ring Resonators. From the Navier equations we derive that the lowest resonant frequencies are associated with localised bending modes solutions of a fourth order differential equation in thin bridges, which are responsible for the appearance of a low frequency stop band. Potential ...
