Abstract :
A frequency domain terahertz spectroscopy system was developed to operate from 210-270 GHz. A multiplier chain ending with a broadband sextupler provides several milliwatts of power, and a heterodyne receiver measures the transmission through materials under test with better than 0.5% accuracy.
