Compacted tunable split-ring resonators

Tunable Superconducting Split Ring Resonators

Capacitor-loaded split ring resonators as tunable metamaterial components

Transmission through split ring resonator SRR structures loaded with capacitors is investigated both experimentally and numerically. Magnetic resonance frequency m is observed to shift to lower frequencies when capacitors are mounted to the various capacitive regions of the SRR structure. The amount of change in m depends strongly on the place where the capacitors are loaded. The magnetic reson...

Tunable split-ring resonators for nonlinear negative-index metamaterials.

We study experimentally the dynamic tunability and self-induced nonlinearity of split-ring resonators incorporating variable capacitance diodes. We demonstrate that the eigenfrequencies of the resonators can be tuned over a wide frequency range, and significantly, we show that the self-induced nonlinear effects observed in the varactor-loaded split-ring resonator structures can appear at relati...

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...
