Engineering Electromagnetics

by Kenneth R. Demarest

Using a physically based approach, this book explores the basic theories and equations of electromagnetics and how they are used in engineering practice. Focuses on the physical processes involved in electromagnetic fields and applications. Emphasizes the engineering relevance and use of electromagnetic theory — in both the "theory" chapters and applications chapters. Uses a "classical", or "historical" approach which begins with low frequency field effects (electrostatics and magnetostatics), and leads later to the full time-varying effects. Motivates the mathematics with discussions that tell the reader where the discussion is going, how it will get there, and what the equations mean. Contains a broad overview chapter on Electromagnetic Sources, Forces, and Fields (Ch. 3) that explains what electric and magnetic fields are, in general, and how they are related to their sources. Discusses the classic electromagnetic experiments that were performed in the early history of electromagnetics, along with the laws that came from electromagnetic equations — Maxwell's equations. Covers transmission lines before plane waves. This Smoother, earlier coordination with laboratory experiments and measuring instruments that make heavy use of transmission lines. Earlier development of the relationship between electromagnetic theory and circuit theory. Arranges chapters on electrostatic fields and effects (Chs. 4-6) and those on magnetostatic fields and effects (Chs. 7-9) in parallel fashion;this organization presents the material in manageable units. Presents the curvilinear square techniques (flux plots) for graphically solving both electrostatic and magnetostatic boundary value problems. Coverage of transmission lines includes both time-domain and frequency domain analysis. Considers topics not usually covered in other similar texts rise time on printed-circuit board transmission lines; the transient response of transmission lines with nonlinear loads, such as diodes. Makes extensive use of equivalent circuits to model many aspects of transmission line performance. Discusses all the traditional microwave waveguide topics , plus optical waveguides, fiber optic cables , and fiber optic systems. Covers a wide range of antenna types and discusses radiation and antenna parameters.
