Abstract
We present a tabletop-scale realization of a tunable metamaterial platform to control surface acoustic waves (SAWs). The platform comprises an array of ferromagnetic beads controlled with permanent magnets, arranged atop an elastic substrate. We demonstrate the possibility of shifting the beads resonances and, in turn, tuning the SAWs bandgaps.
