IGF::OT::IGF THE GOAL OF THIS RESEARCH IS TO DEVELOP HIGH-FREQUENCY FARADAY ROTATION ISOLATORS THAT EXHIBIT SIGNIFICANTLY REDUCED LOSS, HIGHER POWER HANDLING AND IMPROVED BANDWIDTH OVER COMMERCIALLY AVAILABLE PRODUCTS. THE BANDWIDTH LIMITATIONS OF HIGH-FREQUENCY CIRCULATORS WILL BE EXPLORED. IT WAS DEMONSTRATED IN THE PHASE I WORK THAT THE BANDWIDTH OF THESE COMPONENTS CAN BE SUBSTANTIALLY INCREASED THROUGH IMPEDANCE MATCHING TECHNIQUES. AT THE END OF THE PHASE II PROGRAM, MICRO HARMONICS WILL HAVE DEVELOPED A FULL LINE OF ISOLATORS OPERATING IN BANDS FROM WR-12 THROUGH WR-3 AND CIRCULATORS WORKING IN BANDS FROM WR-15 THROUGH WR-5. IN THE PHASE I WORK OUR MODELS WERE PROVEN TO BE ACCURATE. THE APPROACH IS FUNDAMENTALLY SOUND, BUT THERE ARE SIGNIFICANT TECHNICAL CHALLENGES. THESE COMPONENTS WILL FIND IMMEDIATE USE IN A BROAD RANGE OF SYSTEMS USED BY NASA AS WELL AS THE COMMERCIAL SECTOR.
