ADVANCED CLASSICAL ELECTROMAGNETISM 2022 (H) ISBN： 9780691220390 類別： 物理學Physics 出版社： PRINCETON UNIVERSITY PRESS 作者： WALD 年份： 2022 裝訂別： 精裝 頁數： 248頁 Electromagnetism is one of the pillars of modern physics. Robert Wald provides graduate students with a clear, concise, and mathematically precise introduction to the subject, covering all the core topics while bringing the teaching of electromagnetism up to date with our modern understanding of the subject. Electromagnetism is usually taught in a quasi-historical fashion, starting from concepts formulated in the eighteenth and nineteenth centuries, but this tends to promote outdated ways of thinking about the theory. Wald begins with Maxwell’s equations—the foundation of electromagnetism—together with the formulas for the energy density, momentum density, and stress tensor of the electromagnetic field. He then proceeds through all the major topics in classical electromagnetism, such as electrostatics, dielectrics, magnetostatics, electrodynamics and radiation, diffraction, and special relativity. The last two chapters discuss electromagnetism as a gauge theory and the notion of a point charge—topics not normally treated in electromagnetism texts. > Completely rethinks how to teach electromagnetism to first-year graduate students > Presents electromagnetism from a modern, mathematically precise perspective, formulating key conceptual ideas and results clearly and concisely > Written by a world-class physicist and proven in the classroom > Covers all the subjects found in standard electromagnetism textbooks as well as additional topics such as the derivation of the initial value formulation for Maxwell’s equations > Also ideal as a supplementary text or for self-study Table Of Contents Preface CHAPTER 1 Introduction: Electromagnetic Theory without Myths 1.1 The Fundamental Electromagnetic Variables Are the Potentials, Not the Field Strengths 1.2 Electromagnetic Energy, Momentum, and Stress Are an Integral Part of the Theory 1.3 Electromagnetic Fields Should Not Be Viewed as Being Produced by Charged Matter 1.4 At a Fundamental Level, Classical Charged Matter Must Be Viewed as Continuous Rather Than Point-Like CHAPTER 2 Electrostatics 2.1 Uniqueness of Solutions in Electrostatics 2.2 Point Charges and Green’s Functions 2.3 Interaction Energy and Force 2.4 Multipole Expansion of the Green’s Function 2.5 Conducting Cavities; Dirichlet and Neumann Green’s Functions Problems CHAPTER 3 Dielectrics 3.1 Macroscopic Description of Dielectrics 3.2 Force and Interaction Energy Problems CHAPTER 4 Magnetostatics 4.1 The Equations of Magnetostatics 4.2 Multipole Expansion 4.3 Interaction Energy and Force 4.4 Magnetic Materials Problems CHAPTER 5 Electrodynamics 5.1 The Equations of Electrodynamics 5.2 Retarded Green’s Function 5.3 Multipole Expansion 5.3.1 Cartesian Multipole Expansion of the Radiation Field for a Nonrelativistic Source 5.3.2 General Multipole Expansion for a Relativistic Source ...

【簡介】 Balanis’ third edition of Advanced Engineering Electromagnetics - a global best-seller for over 30 years - covers the advanced knowledge engineers involved in electromagnetics need to know, particularly as the topic relates to the fast-moving, continuously evolving, and rapidly expanding field of wireless communications. The immense interest in wireless communications and the expected increase in wireless communications systems projects (antennas, microwaves and wireless communications) points to an increase in the number of engineers needed to specialize in this field.Highlights of the 3rd Edition include: ●A new chapter, on Artificial Impedance Surfaces (AIS), contains material on current and advanced EM technologies, including the exciting and fascinating topic of metasurfaces for: 1.Control and broadband RCS reduction using checkerboard designs. 2.Optimization of antenna fundamental parameters, such as: input impedance, directivity, realized gain, amplitude radiation pattern. 3.Leaky-wave antennas using 1-D and 2-D polarization diverse-holographic high impedance metasurfaces for antenna radiation control and optimization. 4.Associated MATLAB programs for the design of checkerboard metasurfaces for RCS reduction, and metasurface printed antennas and holographic L WA for radiation control and optimization. ●Throughout the book, there are: 1.Additional examples, numerous end-of-chapter problems, and PPT notes. 2.Fifty three MATLAB computer programs for computations, graphical visualizations and animations. 3.Nearly 4,500 multicolor PowerPoint slides are available for self-study or lecture use. CONSTANTINE A. BALANIS is Regents Professor Emeritus of Electrical Engineering at Arizona State University, USA. He received his BSEE from Virginia Tech in 1964, his MEE from the University of Virginia in 1966, his PhD in Electrical Engineering from The Ohio State University in 1969, and an honorary doctorate from the Aristotle University of Thessaloniki (AUTH). Professor Balanis is a Life Fellow of IEEE, author of Antenna Theory: Analysis and Design, and editor of Modern Antenna Handbook, both published by Wiley. 【目錄】 1 Time-Varying and Time-Harmonic Electromagnetic Fields 2 Electrical Properties of Matter 3 Wave Equation and Its Solutions 4 Wave Propagation and Polarization 5 Reflection and Transmission 6 Auxiliary Vector Potentials, Construction of Solutions, and Radiation and Scattering Equations 7 Electromagnetic Theorems and Principles 8 Rectangular Cross-Section Waveguides and Cavities 9 Circular Cross-Section Waveguides and Cavities 10 Spherical Transmission Lines and Cavities 11 Scattering 12 Integral Equations and the Moment Method 13 Geometrical Theory of Diffraction 14 Diffraction by a Wedge with Impedance Surfaces 15 Green’s Functions 16 Artificial Impedance Surfaces Appendix I Identities Appendix II Vector Analysis Appendix III Fresnel Integrals Appendix IV Bessel Functions Appendix V Legendre Polynomials and Functions Appendix VI the Method of Steepest Descent (saddle-point Method)
