Providing coverage on all aspects of microwave superconductivity this book includes information on: fundamentals, fabrication of thin and thick films, measurement, components, circuits, cryogenic packaging and market potential. The applications examined, using either active or passive circuit elements, include those based on both the older metal-based superconductors, operating at liquid-helium temperatures, and the newer ceramic-based superconductors, operating at liquid-nitrogen temperatures. Applications that are covered in detail include filters, resonators and antennae for wireless communications and military systems, space-based cryoelectronics, RF SQUIDs and DC SQUID amplifiers, NMR and MRI coils, accelerator cavities, and Josephson flux-flow devices in the millimetre and sub-millimetre regimes. This book is intended for use as a textbook in an electrical engineering graduate course in microwave superconductivity or as a reference book for microwave engineers.

The genesis of the NATO Advanced Study Institute (ASI) upon which this volume is based, occurred during the summer of 1986 when we came to the realization that there had been significant progress during the early 1980's in the field of superconducting electronics and in applications of this technology. Despite this progress, there was a perception among many engineers and scientists that, with the possible exception of a limited number of esoteric fundamental studies and applications (e.g., the Josephson voltage standard or the SQUID magnetometer), there was no significant future for electronic systems incorporating superconducting elements. One of the major reasons for this perception was the aversion to handling liquid helium or including a closed-cycle helium liquefier. In addition, many critics felt that IBM's cancellation of its superconducting computer project in 1983 was "proof" that superconductors could not possibly compete with semiconductors in high-speed signal processing. From our perspective, the need for liquid helium was outweighed by improved performance, i. e., higher speed, lower noise, greater sensitivity and much lower power dissipation. For many commercial, medical, scientific and military applications, these attributes can lead to either enhanced capability (e.g., compact real-time signal processing) or measurements that cannot be made using any other technology (e.g., SQUID magnetometry to detect neuromagnetic activity).
