During the last decade a new generation of software tools has evolved in computational electromagnetics. Both analyti cal methods and particularly numerical techniques have improved considerably, leading to an extended range of capabilities and an increased applicability of both dedicated and general purpose computer codes. It is the intention of this volume to review the state of the art in electromagnetic analysis and design, and to describe the fundamentals and the advances in theoreti cal/numerical approaches coupled with practical solutions for static and time-dependent fields. In this context, the book illustrates the effectiveness of numerical techniques and associated computer codes in solving real electromagnetic field problems. In addition, it demonstrates the usefulness of modern codes for the analysis of many industrial practical cases. In particular, solutions of magnetostatic and magnetodynamic problems applied to electrical machines, induction heating, non destructive testing, fusion reactor technology and other industrial are presented and discussed. The present volume reflects and combines the lectures which are organized in the frame of the Eurocourse programme at JRC Ispra under the sponsorship of the Institute for Sys tems Engineering and Informatics (ISEI). It is hoped that in this context the Institute and particularly the Systems Engineering & Reliability (SER) Division can play a stimulating role in sponsoring and promoting the diffusion of knowledge in novel areas of computer and information science.
