THz detectors based on electromechanical meta-atoms

We will present a THz electromechanical meta-atom that can be used as a fast, room-temperature detector for THz waves. Contrary to the majority of infrared and THz electromechanical devices, our meta-atom is based on electric interactions instead of photothermal forces. We can thus overcome the finite response time imposed by heat diffusion and realize detectors with virtually no upper limit in the modulation bandwidth.
