Opis: Electromagnetic Boundary Problems - David Chang, Edward Kuester

Electromagnetic Boundary Problems introduces the formulation and solution of Maxwell's equations describing electromagnetism. Based on a one-semester graduate-level course taught by the authors, the text covers material parameters, equivalence principles, field and source (stream) potentials, and uniqueness, as well as: * Provides analytical solutions of waves in regions with planar, cylindrical, spherical, and wedge boundaries * Explores the formulation of integral equations and their analytical solutions in some simple cases * Discusses approximation techniques for problems without exact analytical solutions * Presents a general proof that no classical electromagnetic field can travel faster than the speed of light * Features end-of-chapter problems that increase comprehension of key concepts and fuel additional research Electromagnetic Boundary Problems uses generalized functions consistently to treat problems that would otherwise be more difficult, such as jump conditions, motion of wavefronts, and reflection from a moving conductor. The book offers valuable insight into how and why various formulation and solution methods do and do not work. "... a unique title by two authors whose in-depth knowledge of this material and ability to present it to others are hardly matched. While the book provides distinguishing coverage and presentation of many topics, some discussions cannot be found elsewhere. I highly recommend this outstanding piece, bringing great value as both a textbook and reference text." -Branislav M. Notaros, Colorado State University, Fort Collins, USA "... useful for students, researchers, engineers, and teachers of electromagnetics. Today, in many universities, this discipline is taught by teachers who do not have much research experience in electromagnetism. That is why this textbook, written by world-known specialists and showing how electromagnetics courses should be built and taught, is very important. The authors have made clearer several aspects of electromagnetism which are poorly highlighted in earlier-published literature." -Guennadi Kouzaev, Norwegian University of Science and Technology, TrondheimList of Figures List of Tables Preface Author Bios Maxwell's Equations and Sources Maxwell Equations in Free Space Energy Transfer and Poynting's Theorem Macroscopic Maxwell Equations in Material Media Multipole Expansions for Charges and Currents Averaging of Charge and Current Densities Conduction, Polarization, and Magnetization Time-Harmonic Problems Duality;
