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

Issak D. Mayergoyz

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. The key features include: it contains extensive use of analytical techniques for the solution of nonlinear problems of electromagnetic field diffusion. It features simple analytical formulas for surface impedances of nonlinear and hysteretic media and offers an analysis of nonlinear diffusion for linear, circular and elliptical polarizations of electromagnetic fields. It also offers a novel and extensive analysis of eddy current losses in steel laminations for unidirectional and rotating magnetic fields. It offers a preisach approach to the modeling of eddy current hysteresis and superconducting hysteresis and includes an extensive study of nonlinear diffusion in superconductors with gradual resistive transitions (scalar and vectorial problems).
