Introduction to Superconducting CircuitsSuperconductivity made accessible-a unique introduction. Does superconductivity have to be hard to understand? No, says Alan Kadin, as he proceeds to make the field accessible to engineers, applied physicists, even undergraduate students in electrical engineering. Setting advanced theories aside, Dr. Kadin uses simple circuit models to develop an understanding of the physics of superconductors, then applies this knowledge to superconducting circuits and systems. He covers cutting-edge circuit applications and materials along with practical examples-giving readers insight into the pros and cons of various superconductors and what superconductivity has to offer for different disciplines. End-of-chapter problems as well as numerous conceptual line drawings, circuit schematics, and plots complement the following topics: * The central role of inductance and kinetic inductance. * Transmission line model for RF and dc properties. * Dual circuit transformations to follow vortex and fluxon motion. * A balanced coverage of low-temperature and high-temperature superconductors. * Both large-scale (power) and small-scale (electronic) applications. * Applications of superconducting devices to electromagnetic radiation detectors. * The use of SPICE to simulate Josephson junctions and circuits. *An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department. |
