Engineering Electromagnetics: International Edition - Tapa blanda

Sinopsis

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 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 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. * 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 e.g.: 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.
