Persistent Tuning of Metamaterials

ORAL

Abstract

Methods for real-time tuning (dynamic-tuning) of metamaterial electromagnetic response have received significant attention as a possible approach to alleviate limitations associated with bandwidth in metamaterials. In a dynamic-tuning configuration, an applied stimulus induces some temporary change in the metamaterial properties -- altering the metamaterial response as long as the stimulus remains. In this talk, we discuss results from a SRR-VO$_{2}$ hybrid metamaterial which exhibits electrically-controlled persistent tuning.\footnote{T.Driscoll et.al. Science. 325, 1518 (2009)} Persistent tuning allows lasting modification to the metamaterial response using a transient stimulus. Such ability is highly desirable in consideration of potential metamaterial applications, such as reconfigurable optics.
