Time-domain signals measured at frequencies of 10 kHz (a), 20 kHz (b), 60 kHz (c), and 100 kHz (d). In the figures, solid lines represent the monitoring signals output by the signal source (MS). Solid scatter plots represent the time-domain signals output by the photodetector when the TEM cell is forward-fed (+fed). Hollow scatter plots represent the time-domain signals output by the photodetector when the TEM cell is reverse-fed (−fed) (Methods).
