Roadmap to electrically self-tuning metamaterials: Design and experimental validation

We present the design and experimental validation of a self-tuning metamaterial. We begin with an active two-state split ring resonator and build up to a self-contained system that includes feedback. We show the ability of the active split ring resonator to track and lock to an incident RF signal around 1 GHz. The SRR has a tuning capability of 4% bandwidth and takes a maximum of 3 seconds to track and lock to an incident signal.
