Electromagnetic Waves Materials And Computation With Matlab

Readily available commercial software enables engineers and students to perform routine calculations and design without necessarily having a sufficient conceptual understanding of the anticipated solution. The software is so user-friendly that it usually produces a beautiful colored visualization of that solution, often camouflaging the fact that t

"This two-volume set consists of "Principles of Electromagnetic Waves and Materials, Second Edition" and "Advanced Electromagnetic Computation, Second Edition". Volume I takes an integrative approach to the subject of electromagnetics by supplementing quintessential "old school" information and methods with MATLAB® software. Volume II consists of advanced electromagnetic computation which focuses on Algorithms of Finite Differences, Moment Method, Finite Element method and Finite Difference Time Domain method. Hand-computed simple examples and MATLAB-coded simple examples with only a few elements are used to explain the concepts behind the algorithms. Four new chapters are included.

"Preface The subject of electromagnetics is still a core subject of the undergraduate electrical engineering (EE) curriculum; however, at most of the universities in United States, the time allotted to teach it is cut into half (one 3-credit course instead of two). The present graduates with BS degree in EE being rushed through the same curriculum content in a shorter time often miss the concepts and depend on a lot of formulas which they use as a recipe for some calculations based on an example worked out in the book. Some of them are fortunate to take a follow-up special elective course in microwaves or RF design or antennas or fiber optics, and so on, thus partly reinforcing one application area. Readily available commercial software allows them to do routine calculations and design without having a conceptual understanding of the expected solution. The commercial software is so user-friendly that we usually get a beautiful colored visualization of the solution, even if it is a wrong simulation of the physical problem. After getting one or two mild reprimands from the boss in his new employment after graduation, the new graduate realizes that he needs to have a fairly good idea of what is the appropriate model to be simulated and what qualitative result is to be expected. Though the software is very useful, it is not a substitute for a conceptual understanding of the steps involved in solving the problem. Fortunately, for him, there is probably a university which offers graduate courses and there is an instructor/professor who understands that these bright students recruited by some of the top companies are not less smart than the employees recruited by the company, say a decade or two ago"--

Advanced Electromagnetic Computation with MATLAB® discusses commercial electromagnetic software, widely used in the industry. Algorithms of Finite Differences, Moment method, Finite Element method and Finite Difference Time Domain method are illustrated. Hand-computed simple examples and MATLAB-coded examples are used to explain the concepts behind the algorithms. Case studies of practical examples from transmission lines, waveguides, and electrostatic problems are given so students are able to develop the code and solve the problems. Two new chapters including advanced methods based on perturbation techniques and three dimensional finite element examples from radiation scattering are included.

Principles of Electromagnetic Waves and Materials is a condensed version of the author's previously published textbook, Electromagnetic Waves, Materials, and Computation with MATLAB(R). This book focuses on lower-level courses, primarily senior undergraduate and graduate students in electromagnetic waves and materials courses. It takes an integrative approach to the subject of electromagnetics by supplementing quintessential "old-school" information and methods with the appropriate amount of material on plasmas for exposing the students to the broad area of Plasmonics and by striking a balance between theoretical and practical aspects.

This fourth edition of the text reflects the continuing increase in awareness and use of computational electromagnetics and incorporates advances and refinements made in recent years. Most notable among these are the improvements made to the standard algorithm for the finite-difference time-domain (FDTD) method and treatment of absorbing boundary conditions in FDTD, finite element, and transmission-line-matrix methods. It teaches the readers how to pose, numerically analyze, and solve EM problems, to give them the ability to expand their problem-solving skills using a variety of methods, and to prepare them for research in electromagnetism. Includes new homework problems in each chapter. Each chapter is updated with the current trends in CEM. Adds a new appendix on CEM codes, which covers commercial and free codes. Provides updated MATLAB code.
