Nonlinear Diffusion of Electromagnetic Fields: with Applications to Eddy Currents and Superconductivity

From Book News, Inc.
Mayergoyz (electrical engineering, U. of Maryland) contends that his in-depth coverage of nonlinear diffusion of electromagnetic fields"nonlinear" since described by nonlinear partial differential equations fills a gap in the field despite significant theoretical and practical interest. He includes analyses for: surface impedances of nonlinear and hysteretic media, eddy current losses in steel laminations, and nonlinear diffusion in superconductors with gradual resistive transitions. Intended for a broad audience of design engineers and researchers immersed in electric machines, induction heating, superconductors, CAD software in electromagnetics, and magnetic components in power electronics. The Preisach model of hysteresis is appended. Book News, Inc.®, Portland, OR


Book Description
Nonlinear Diffusion of Electromagnetic Fields covers applications of the phenomena of non-linear diffusion of electromagnetic fields, such as magnetic recording, electromagnetic shielding and non-destructive testing, development of CAD software, and the design of magnetic components in electrical machinery. The material presented has direct applications to the analysis of eddy currents in magnetically nonlinear and hysteretic conductors and to the study of magnetization processes in electrically nonlinear superconductors. This book will provide very valuable technical and scientific information to a broad audience of engineers and researchers who are involved in these diverse areas.
