Engineering Electromagnetics - Tapa blanda

De la contraportada

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