Reviews the fundamental concepts behind the theory and computation of electromagnetic fields The book is divided in two parts. The first part covers both fundamental theories (such as vector analysis, Maxwell’s equations, boundary condition, and transmission line theory) and advanced topics (such as wave transformation, addition theorems, and fields in layered media) in order to benefit students at all levels. The second part of the book covers the major computational methods for numerical analysis of electromagnetic fields for engineering applications. These methods include the three fundamental approaches for numerical analysis of electromagnetic fields: the finite difference method (the finite difference time-domain method in particular), the finite element method, and the integral equation-based moment method. The second part also examines fast algorithms for solving integral equations and hybrid techniques that combine different numerical methods to seek more efficient solutions of complicated electromagnetic problems. Theory and Computation of Electromagnetic Fields, Second Edition: Provides the foundation necessary for graduate students to learn and understand more advanced topics Discusses electromagnetic analysis in rectangular, cylindrical and spherical coordinates Covers computational electromagnetics in both frequency and time domains Includes new and updated homework problems and examples Theory and Computation of Electromagnetic Fields, Second Edition is written for advanced undergraduate and graduate level electrical engineering students. This book can also be used as a reference for professional engineers interested in learning about analysis and computation skills.

Dieses eingeführte, didaktisch hervorragende Lehrbuch vereinigt Anschaulichkeit mit außerordentlicher Genauigkeit in der Begriffsbildung und in den Ableitungen. Vermittelt werden die elektromagnetische Feldtheorie und die dafür erforderlichen mathematischen Methoden. Die Maxwellschen Gleichungen werden vorgestellt und erläutert. Es folgen Ausführungen über Elektrostatik, Strömungsprobleme, Magnetostatik, quasistationäre Felder und elektromagnetische Wellen. Der Autor behandelt die Anwendung numerischer Methoden wie finite Differenzen, finite Elemente, Randelemente, Ersatzladungsmethoden und Monte-Carlo-Methoden auf feldtheoretische Probleme. Er gibt Ausblicke auf grundlegende, z.T. noch offene Fragen der Physik bis hin zur Quantenmechanik. Ein Kapitel über die spezielle Relativitätstheorie, mit deren Hilfe sich zahlreiche Probleme der elektromagnetischen Feldtheorie leichter lösen lassen, rundet das Werk ab. In der 6. Auflage wurden Korrekturen durchgeführt. Ein Buch nicht nur für Ingenieurstudenten, sondern auch für Studenten der Physik und anderer Fachrichtungen.

Although topology was recognized by Gauss and Maxwell to play a pivotal role in the formulation of electromagnetic boundary value problems, it is a largely unexploited tool for field computation. The development of algebraic topology since Maxwell provides a framework for linking data structures, algorithms, and computation to topological aspects of three-dimensional electromagnetic boundary value problems. This book attempts to expose the link between Maxwell and a modern approach to algorithms. The first chapters lay out the relevant facts about homology and cohomology, stressing their interpretations in electromagnetism. These topological structures are subsequently tied to variational formulations in electromagnetics, the finite element method, algorithms, and certain aspects of numerical linear algebra. A recurring theme is the formulation of and algorithms for the problem of making branch cuts for computing magnetic scalar potentials and eddy currents. Appendices bridge the gap between the material presented and standard expositions of differential forms, Hodge decompositions, and tools for realizing representatives of homology classes as embedded manifolds.

A new edition of the leading textbook on the finite element method, incorporating major advancements and further applications in the field of electromagnetics The finite element method (FEM) is a powerful simulation technique used to solve boundary-value problems in a variety of engineering circumstances. It has been widely used for analysis of electromagnetic fields in antennas, radar scattering, RF and microwave engineering, high-speed/high-frequency circuits, wireless communication, electromagnetic compatibility, photonics, remote sensing, biomedical engineering, and space exploration. The Finite Element Method in Electromagnetics, Third Edition explains the method’s processes and techniques in careful, meticulous prose and covers not only essential finite element method theory, but also its latest developments and applications—giving engineers a methodical way to quickly master this very powerful numerical technique for solving practical, often complicated, electromagnetic problems. Featuring over thirty percent new material, the third edition of this essential and comprehensive text now includes: A wider range of applications, including antennas, phased arrays, electric machines, high-frequency circuits, and crystal photonics The finite element analysis of wave propagation, scattering, and radiation in periodic structures The time-domain finite element method for analysis of wideband antennas and transient electromagnetic phenomena Novel domain decomposition techniques for parallel computation and efficient simulation of large-scale problems, such as phased-array antennas and photonic crystals Along with a great many examples, The Finite Element Method in Electromagnetics is an ideal book for engineering students as well as for professionals in the field.

This classic 1968 edition of Field Computation by Moment Methods is the first book to explore the computation of electromagnetic fields by the method of moments--the most popular method for the numerical solution of electromagnetic field problems. It presents a unified approach to moment methods by employing the concepts of linear spaces and functional analysis. Written especially for those who have a minimal amount of experience in electromagnetic theory, theoretical and mathematical are illustrated by examples that prepare all readers with the skills they need to apply the method of moments to new, engineering-related problems.

Intended for undergraduate students of electrical engineering, this introduction to electromagnetic fields emphasizes the computation of fields as well as the development of theoretical relations. The first part thus presents the electromagnetic field and Maxwell's equations with a view toward connecting the disparate applications to the underlying relations, while the second part presents computational methods of solving the equations - which for most practical calses cannot be solved analytically.

Physikalische Theorien sind ohne grA1/4ndliche Kenntnisse A1/4ber deren mathematische Grundlagen nur schwer zu erfassen un kaum sinnfAllig zu nutzen. Elektrik und Magnetismus - ohne Wissen A1/4ber Verktoren und Felder im Raum? Klassische und Quantenmechanik - ohne Kenntnisse A1/4ber Transformationen, Matrizen und Operatoren? Wong versteht solcherart nAtiges Wissen ohne Weitschweifigkeit - der Denkweise des Physikers, mehr noch dem jeweiligen Kenntnisstand des Studenten angemessen - zu vermitteln. EinfA1/4hrend, kurz und prAzise, mit der langen Erfahrung des Hochschullehrers. Daher ein selten geglA1/4cktes Lehr- aber auch Handbuch zugleich, versehen mit Aoebungen und dem nAtigen Formelwerk.
