Written by the inventor of the ultrahigh Q-value resonator, this text describes innovations in high-temperature superconducting (HTS) microwave circuits and explains the fundamental principles. The book shows how to analyze, design, characterize and test the circuits created. Each chapter gives application information on: materials and characterization; transmission lines; passive components; active devices; HTS/III device hybrid circuits; high Q-value resonators; and packaging. Augmented with 202 equations and 137 illustrations, "High-Temperature Superconducting Microwave Cricuits" offers information for microwave engineers, system engineers, and material scientists. University students should find the text useful for learning about the next generation of microwave circuits.
