Abstract :
A meta-surface with electromechanically switchable diamagnetic terahertz meta-molecules is presented and experimentally demonstrated. The presented reconfigurable meta-surface enables record-high modulation depths and modulation bandwidths at terahertz frequencies, without a compromise on modulation speed and modulation voltage.
