Description:

Electromagnetism is a notoriously difficult subject to teach. Although modern life is entirely enabled by electromagnetic effects, it is less intuitive to grasp electromagnetism compared with, say, mechanics, where it is possible to see all the parts of a system working, and to literally feel effects of forces or torque. Therefore, although electromagnetism is a very beautiful branch of physics with some elegant mathematics, it is deemed to be inaccessible by many students. At University level, there is a need for electrical and electronic engineers in particular to have a good understanding of electromagnetism and how it impacts upon communications, power generation and transmission, semiconductor devices, motors, etc. The aim of this book is to develop an engineering student's understanding of electromagnetism in the context of real effects and how they apply to such applications, whilst retaining all of the power of the elegant mathematics that can be used to give insight. Section 1 covers the fundamentals of electromagnetism. This includes the basics of electric and magnetic fields and their expression through the Maxwell equations, and also how they interact with materials like semiconductors, piezoelectrics, magnets, etc. Section 2 then considers the application of electromagnetism to transmission lines, antennas, and waveguides. This is an introductory undergraduate textbook which would then lead on to specialist textbooks on given application areas (e.g. radio communications), but also a useful refresher for professional engineers.
