The proposed ferrite components would find immediate application in heterodyne receivers used in NASA's Submillimeter Missions such as Marvel, VESPER, MACO as well as earth observing satellites such as SIRICE. They are also useful in a broad range of laboratory instrumentation for the development of millimeter-wave and submillimeter-wave sources, detectors, receivers and systems. They are broadly used in scientific instruments for plasma diagnostics (ITER), chemical spectroscopy, biomaterial analysis, and radio astronomy. These components are fundamental building blocks that find application in virtually any system working at millimeter-wave, submillimeter-wave and terahertz frequencies. High frequency ferrite components find a broad range of application in military systems that include compact range radar, imaging systems, covert communications systems, and chemical and bio-agent detection systems. There are potential applications in biomedical systems for the real time analysis of skin diseases, portal security scanners, high frequency data links and industrial process control systems. There is an immediate need for these components in frequency extension modules for vector network analyzers operating from 75 GHz to over 500 GHz. They are fundamental building blocks used in many systems operating in millimeter-wave to terahertz frequency bands.
