We have demonstrated a three-dimensional movable metamaterial (MM) with reconfigurable electric split-ring resonators (eSRR) at terahertz frequencies. This is accomplished by making planar arrays of eSRR with movable stress curved beams (eSRR-MSCBs) which are actuated out-of-plane by electrostatic force. Our results have demonstrated that the eSRR-MSCBs possess blueshifting capabilities and polarization dependent state at terahertz frequencies, while such adaptive MMs offer significant potential in realizing electromagnetic functionality with diversified applications, such as sensors, switches, and filters.
