Using sub-THz and THz wave sources (BWOs), this transmission-type EPR/ESR spectrometer can be quasi-continuously frequency-tuned via applied voltage.
The sub-THz and THz wave sources used in the BWO-based spectrometer can also be used independently in EPR/ESR-type experiments. So far they have been successfully used in conjunction with the Keck 25-T resistive magnet, the SCMM 20-T superconducting magnet, and the EMR 15/17-T superconducting magnet. Given a proper probe, they can be employed with other magnets as well.
