Electromagnetic Foundations of Electrical Engineering

The applications of electromagnetic phenomena within electrical
engineering have been evolving and progressing at a fast pace. In
contrast, the underlying principles have been stable for a long
time and are not expected to undergo any changes. It is these
electromagnetic field fundamentals that are the subject of
discussion in this book with an emphasis on basic principles,
concepts and governing laws that apply across the electrical
engineering discipline.

Electromagnetic Foundations of Electrical Engineering
begins with an explanation of Maxwell's equations, from which
the fundamental laws and principles governing the static and
time-varying electric and magnetic fields are derived. Results for
both slowly- and rapidly-varying electromagnetic field problems are
discussed in detail.

Key aspects:

• Offers a project portfolio, with detailed solutions included on
  the companion website, which draws together aspects from various
  chapters so as to ensure comprehensive understanding of the
  fundamentals.

• Provides end-of-chapter homework problems with a focus on
  engineering applications.

• Progresses chapter by chapter to increasingly more challenging
  topics, allowing the reader to grasp the more simple phenomena and
  build upon these foundations.

• Enables the reader to attain a level of competence to
  subsequently progress to more advanced topics such as electrical
  machines, power system analysis, electromagnetic compatibility,
  microwaves and radiation.

This book is aimed at electrical engineering students and
faculty staff in sub-disciplines as diverse as power and energy
systems, circuit theory and telecommunications. It will also appeal
to existing electrical engineering professionals with a need for a
refresher course in electromagnetic foundations.

Auteur
J. A. Brandão Faria received his PhD degree and aggregate title in electrical engineering from the Instituto Superior Técnico of the Technical University of Lisbon, where, since 1994, he has been a Full Professor of Electrical Engineering teaching undergraduate and graduate courses in electromagnetics. His teaching activities also include lecturing courses at the Portuguese Air Force Academy.
Professor Brandão Faria was a senior scientist with the former Centro de Electrotecnia Teórica e Medidas Eléctricas where he served as President from 1994 until 2000. Since 2008, he has been at the recently created CIEEE (Center for Innovation in Electrical Engineering and Energy).
Professor Brandão Faria was the recipient of two Honorable Mentions awarded in 1994 and 2007 by the Portuguese State Department of Science and Technology, and by the Technical University of Lisbon, respectively. His areas of interest include electromagnetic field problems, power lines, and wave propagation phenomena in multiconductor transmission lines. He is the author of two books on electrical engineering subjects, namely Optica and Multiconductor Transmission-Line Structures, and has published over 100 technical papers.
Professor Brandão Faria is a member of the Editorial Board of the European Transactions on Electrical Power (John Wiley & Sons, Ltd) and a senior member of the IEEE.
