Engineering Electromagnetics
Using a physically based approach, this book explores the basic theories and equations of electromagnetics and how they are used in engineering practice.FEATURES:Focuses onthe physical processes involved in electromagnetic fields and applications.Emphasizesthe engineering relevance and use of electromagnetic theory— in both the "theory" chapters and applications chapters.Uses a"classical", or "historical" approachwhich 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.Containsa 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.Discussesthe classic electromagnetic experimentsthat 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 allows: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.Presentsthe curvilinear square techniques(flux plots) for graphically solving both electrostatic and magnetostatic boundary value problems.Coverage of transmission lines includes bothtime-domain and frequency domain analysis.Considerstopics not usually covered in other similar textse.g.: rise time on printed-circuit board transmission lines; the transient response of transmission lines with nonlinear loads, such as diodes.Makes extensive use ofequivalent circuitsto model many aspects of transmission line performance.Discusses allthe traditional microwave waveguide topics, plusoptical waveguides, fiber optic cables, andfiber optic systems.Coversa wide range of antenna typesand discussesradiation and antenna parameters.
