MICROWAVE APPLICATIONS OF HIGH-TEMPERATURE SUPERCONDUCTORS

For at least eight of the first ten years of high-temperature supercon ductivity it has been clear that one of the earliest areas of applicat ion and commercialization of these materials is as passive devices for microwave electronics. At the time of writing the first prototype pro ducts are entering service in the mobile communications industry and a wide range of other devices are at a relatively advanced stage of dev elopment. in the further future one can see a cryogenic integrated tec hnology based on HTS materials and the related functional materials wh ich have emerged within the last ten years.
