Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1990 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theoretical and numerical studies of electromagnetic scattering and radiation from perfectly conducting as well as dielectric bodies are of great importance in the design of various systems, such as airborne targets and antennas. This thesis is an attempt to investigate integral equation and partial differential equation techniques as tools for numerical solution of such problems. These techniques are analyzed and some improvements to existing methods are presented. Some scattering problems involving two-dimensional and body of revolution geometries are solved using these techniques to demonstrate their capabilities and to point out their limitations. The first topic that this thesis addresses is the method of moments technique. To demonstrate the techniques developed, electromagnetic scattering from perfectly conducting as well as dielectric bodies of revolution is considered. There are two major issues addressed in this thesis, in this context. First, the use of quasi-entire-domain basis functions, as an alternative to the more traditional sub-sectional basis functions, is considered. It is shown that using the quasi-entire-domain basis functions results in a reduction in the size of the matrix that needs to be solved. The second major topic that Chapter 2 considers is the problem of electromagnetic scattering from layered and partially coated bodies of revolution. The formulation used to solve these problems as well as some results, are presented. The partial differential equation technique that this thesis considers is the finite-difference method. Chapter 3 discusses the finite-difference method in the frequency domain, while Chapter 4 focuses on the solution of Maxwell's equations in the time domain. Chapter 3 solves the problem of scattering by a conducting body of revolution using the finite-difference method in the frequency domain. The procedure outlined uses the coupled azimuthal potentials introduced by Morgan, Chang, and Mei (20) to obtain two coupled partial differential equations. These equations are then solved over a domain discretized using a boundary-fitted curvilinear coordinate system. The main contribution of this thesis in this respect is the application of the boundary-fitted curvilinear coordinate system to this class of problems. It is demonstrated that using this system eliminates the need for using the staircase approximation that is typically required in the finite-difference methods. Chapter 4 focuses on circumventing the problem of staircase approximation that is traditionally used to model material boundaries in finite-difference time-domain algorithms. In this context, two methods are presented. The first one, referred to in this thesis as the modified stencil approach, allows the use of arbitrarily-shaped quadrilateral grids. The second is similar to the boundary-fitted curvilinear coordinate approach presented in Chapter 3. The methods are compared and contrasted, and the advantages and disadvantages of each method are pointed out.

This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book excerpt: In this work, the problem of electromagnetic scattering of a plane wave incident on a conducting body of revolution is considered. The body is assumed to be situated in infinite homogeneous space. The problem is solved using the method of moments. Use of two different types of expansion and testing functions, namely, sub-domain type and entire-domain type is considered. Results obtained using sub-domain pulse functions and entire-domain Gaussian functions are presented. The relative advantages and disadvantages of each type of basis functions is discussed. Keywords: Electromagnetic scattering, Method of moments, Bodies of revolution, Entire domain functions, Subdomain functions.
