Engineering Electromagnetics(This is a reprint in paperback distributed in South East Asia and published in Hong Kong in 2002. It is otherwise identical to the Springer 1st edition, originally published in February 2000.)
This text not only provides students with a good theoretical understanding of the electromagnetic field equations, it also treats a large number of applications. In fact, no topic is presented unless it is directly applicable to engineering design or unless it is needed for the understanding of another topic. In electrostatics, for example, the text includes discussions of photocopying, ink-jet printing, electrostatic separation and deposition, paint spraying, and powder coating. In magnetism, the applications discussed include electric motors and generators, permanent magnets, nuclear magnetic resonance, magnetic recording, and electromagnetic braking. Magnetic force, torque, and magnetic energy are discussed in the context of electric motors and transformers; the applications discussed include linear induction motors, electromagnetic propulsion, magneto-hydrodynamic power generation, and nondestructive testing of materials. The discussion ofel ectromagnetic waves includes such applications as the use of electromagnetic waves for materials processing, microwave detection of substances, remote sensing of the earth and its resources, applications of new materials, and the use of so-called stealth materials in aerospace systems. More than 300 fully worked examples and 700 problems and exercises help students clarify and test their knowledge.
