Abstract

We establish insulator-to-metal transition (IMT) in Vanadium dioxide (VO2) by millimeter-wave (mm-wave) actuation, using two coupled dipole antennas: a simple one as a continuous mm-wave-source and the other one with an embedded VO2 part as an absorber. We measured vertical bar S-12 vertical bar by a vector network analyzer (VNA), to show how the induced mm-wave power in insulating biased VO2 causes INIT. The bias voltage is set to enhance the sensitivity in VO2. The VO2 embedded antenna shows sensitivity to the mm-wave power down to 3.2 mu W. The experiment proves the detection concept also for terahertz frequencies.
