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.

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.

Die elektromagnetische Feldtheorie ist ein für Ingenieure und Naturwissenschaftler grundlegendes Wissensgebiet, das die Gesetzmäßigkeiten elektrischer und magnetischer Felder und Wellen beschreibt. In diesem didaktisch ausgearbeiteten Lehrbuch werden die elektromagnetische Feldtheorie und die dafür erforderlichen mathematischen Methoden vermittelt. Dafür hat der Autor die Lehrinhalte möglichst anschaulich aufbereitet, die Begriffsbildungen und Ableitungen legt er äußerst genau dar. Zu Beginn werden die Maxwellschen Gleichungen, die die Grundlage der klassischen Elektrodynamik bilden, 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 (FEM), Randelemente, Ersatzladungsmethoden und Monte-Carlo-Methoden auf feldtheoretische Probleme. Darüber hinaus gibt er immer wieder Ausblicke auf grundlegende, zum Teil noch offene Fragen der Physik bis hin zur Quantenmechanik. Ein Kapitel widmet sich der Relativitätstheorie, die Maxwells klassische Elektrodynamik erweitert. Denn mithilfe von Einsteins Theorie lassen sich zahlreiche Probleme der elektromagnetischen Feldtheorie leichter lösen. Das Lehrbuch richtet sich an Studierende der ingenieurwissenschaftlichen Fächer und der Physik. Aber auch Studierende anderer naturwissenschaftlicher Fachrichtungen profitieren von diesem Standardwerk zur elektromagnetischen Feldtheorie. Ein Verzeichnis der Symbole und ein Sachverzeichnis erleichtern die Handhabung des Buchs und unterstützen das Lernen.

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.
