Micro Harmonics was just awarded a NASA Phase II SBIR contract to develop cryogenic Faraday rotation isolators in every band from WR-15 (50-75 GHz) through WR-3.4 (220-330 GHz). In the course of this research effort we will also develop room temperature isolators at WR2.8 (260-400 GHz) and WR-2.2 (330-500 GHz) as well as a line [...]
