High Temperature Superconducting Microwave Circuits And Applications

High-temperature superconducting (HTS) materials are becoming more and more attractive in the context of designing RF/microwave filters because of their lower losses and excellent performance. This book focuses on the superconducting microwave filter and its application in modern communication. It first presents the basic principles, HTS materials and processing and then introduces several types of multi-band HTS bandpass filter (BPF), discussing their properties and analyzing equivalent circuit models and their performances. This book is a valuable resource for students and researchers who are interested in wireless communication and RF/microwave design.

Written by the inventor of the ultrahigh Q-value resonator, this book places the latest innovations in high-temperature superconducting (HTS) microwave circuits at your fingertips -- taking you on a guided tour of the fundamental principles and showing you how to analyze, design, characterize, and test the circuits you create.

This book describes the application of new high temperature superconducting materials to microwave devices and systems. It deals with the fundamentals of the interaction between microwaves and superconductors, and includes a basic description of how microwave devices can be constructed using these materials. Since the discovery of high temperature superconductors in 1986 there has been an enormous effort worldwide to develop and characterize these materials. Work on applications has proceeded more slowly however. Nevertheless, commercial applications are now beginning to arise, including use in passive microwave devices. The author carefully describes the advantages of using high temperature superconductors in these devices, enabling scientists and engineers to form a complete understanding of the subject. The rest of the book is devoted to examples of superconducting microwave filters, antennas and systems. The examples chosen relate not only to what can be achieved at present, but indicate the trends for future research and what may be expected for superconducting devices in the future. The book will appeal to researchers in electrical and electronic engineering.

Detailed coverage of all aspects of microwave superconductivity: fundamentals, fabrication, measurement, components, circuits, cryogenic packaging and market potential. Both a graduate-level textbook and a reference for microwave engineers. Applications (with either active or passive circuit elements) include those at both liquid-helium and liquid-nitrogen temperatures. Topics covered include wireless communications, space-based cryoelectronics, SQUIDs and SQUID amplifiers, NMR and MRI coils, accelerator cavities, and Josephson flux-flow devices.

In contrast to research on the fundamental mechanisms of High-Temperature Superconductivity, in recent years we have seen enormous developments in the fabrication and application of High-Tc-superconductors. The two volumes of High Temperature Superconductivity provide a survey of the state of the technology and engineering applications of these materials. They comprise extended original research papers and technical review articles written by physicists, chemists, materials scientists and engineers, all of them noted experts in their fields. The interdisciplinary and strictly application-oriented coverage should benefit graduate students and academic researchers in the mentioned areas as well as industrial experts. Volume 1 "Materials" focuses on major technical advancements in High-Tc materials processing for applications. Volume 2 "Engineering Applications" covers numerous application areas where High-Tc superconductors are making tremendous impact.

Microwave Physics and Techniques discusses the modelling and application of nonlinear microwave circuits and the problems of microwave electrodynamics and applications of magnetic and high Tc superconductor structures. Aspects of advanced methods for the structural investigation of materials and of MW remote sensing are also considered. The dual focus on both HTSC MW device physics and MW excitation in ferrites and magnetic films will foster the interaction of specialists in these different fields.
