Fig. 5: Distribution of the frequency of oscillations based on the mm-wave power.
From: Millimeter-wave to near-terahertz sensors based on reversible insulator-to-metal transition in VO2
a FFT of output waveforms with respect to the applied power, b time domain waveforms of the astable output signal for “no power” and “0 dBm” exposure, c–h the distribution of the frequency of oscillations based on the emitted power from the first port: every waveform is recorded for about 3 s and every cycle is converted to an equivalent frequency to be compared statistically.
