Dynamic Electromagnetics

Drawn from the author's decades of experience teaching the subject, Dynamic Electromagnetics offers a uniquely accessible approach to a discipline often viewed as complicated and mysterious. The text addresses the key principles with extensive problems and examples and provides comprehensive coverage without overwhelming the student with advanced math.Gauss's Law, Surface Integrals, and Electric Fields, Ampère's Law, Line Integrals, and Magnetic Fields, Emf, Field Dynamics, and Maxwell's Equations, Maxwell's Equations and Quasistatic Analysis, Transmission Lines, Time Delay, and Wave Propagation, Steady-State Wave Transmission and Plane Waves, Impedance Matching Techniques and Oblique Waves, Poynting Theorems and Lossy Transmission Lines, Waveguiding and Radiating Structures.For individuals interested in an accessible approach to Electromagnetics.

Intended for advanced undergraduates and graduate students in electrical engineering and physics, this text presents a science-oriented, mathematically complete, and unified approach to the study of field theory and electromagnetics. To facilitate a detailed development of the theoretical material, the authors reject the traditional historical "case study" approach in favor of the theory's logical development, followed by examples that illuminate facets of the theory. The book may be divided into three parts: field analysis, basic electromagnetic theory, and applications. Basic laws and concepts — along with their implications — are thoroughly discussed before detailed mathematical analysis is undertaken. In addition to rigorous treatments of all relevant derivations and proofs, appropriate emphasis is placed upon the physical significance of mathematical operations.

Ultra-wideband (UWB), short-pulse (SP) electromagnetics are now being used for an increasingly wide variety of applications, including collision avoidance radar, concealed object detection, and communications. Notable progress in UWB and SP technologies has been achieved by investigations of their theoretical bases and improvements in solid-state manufacturing, computers, and digitizers. UWB radar systems are also being used for mine clearing, oil pipeline inspections, archeology, geology, and electronic effects testing. Ultra-wideband Short-Pulse Electromagnetics 9 presents selected papers of deep technical content and high scientific quality from the UWB-SP9 Conference, which was held from July 21-25, 2008, in Lausanne, Switzerland. The wide-ranging coverage includes contributions on electromagnetic theory, time-domain computational techniques, modeling techniques, antennas, pulsed-power, UWB interactions, radar systems, UWB communications, broadband systems and components. This book serves as a state-of-the-art reference for scientists and engineers working in these applications areas.

Electromagnetics and Transmission Lines Textbook resource covering static electric and magnetic fields, dynamic electromagnetic fields, transmission lines, antennas, and signal integrity within a single course Electromagnetics and Transmission Lines provides coverage of what every electrical engineer (not just the electromagnetic specialist) should know about electromagnetic fields and transmission lines. This work examines several fundamental electrical engineering concepts and components from an electromagnetic fields viewpoint, such as electric circuit laws, resistance, capacitance, and self and mutual inductances. The approach to transmission lines (T-lines), Smith charts, and scattering parameters establishes the underlying concepts of vector network analyzer (VNA) measurements. System-level antenna parameters, basic wireless links, and signal integrity are examined in the final chapters. As an efficient learning resource, electromagnetics and transmission lines content is strategically modulated in breadth and depth towards a single semester objective. Extraneous, distracting topics are excluded. The wording style is somewhat more conversational than most electromagnetics textbooks in order to enhance student engagement and inclusivity while conveying the rigor that is essential for engineering student development. To aid in information retention, the authors also provide supplementary material, including a homework solutions manual, lecture notes, and VNA experiments. Sample topics covered in Electromagnetics and Transmission Lines include: Vector algebra and coordinate systems, Coulomb’s law, Biot-Savart law, Gauss’s law, and solenoidal magnetic flux Electric potential, Ampere’s circuital law, Faraday’s law, displacement current, and the electromagnetic principles underlying resistance, capacitance, and self and mutual inductances The integral form of Maxwell’s equations from a conceptual viewpoint that relates the equations to physical understanding (the differential forms are also included in an appendix) DC transients and AC steady-state waves, reflections, and standing waves on T-lines Interrelationships of AC steady-state T-line theory, the Smith chart, and scattering parameters Antenna basics and line-of-sight link analysis using the Friis equation An introduction to signal integrity Electromagnetics and Transmission Lines is an authoritative textbook learning resource, suited perfectly for engineering programs at colleges and universities with a single required electromagnetic fields course. Student background assumptions are multivariable calculus, DC and AC electric circuits, physics of electromagnetics, and elementary differential equations.

The Fifth Japan-Hungary Joint Seminar on Applied Electromagnetics in Materials and Computational Technology is held on September 24-26, 1998 in Budapest, Hungary. The Seminar is organised by the Super Tech Consortium (Hungary), the Hungarian Society of Applied Electronics (Hungary) and the Japan Society of Applied Electromagnetics and Mechanics (Japan). The objective of the Seminar is to stimulate the exchange of creative ideas, to promote new achievements by bringing together the engineers and scientists of Japan and Hungary working in the field of applied electromagnetics and related areas as well as to discuss the topics of future co-operative research. A special attention will be paid for the work of young scientists. The scientific program covers the following topics: - Numerical Analysis of Electromagnetic Fields - Material Modelling in Electromagnetic Fields - Electromagnetic Non-destructive Testing and Inverse Problems - High Tc Superconducting Materials and Applications - Controlled Electrical Drives This book will be published as the Proceedings of the Fifth Japan-Hungary Joint Seminar including the selected papers which are presented at the Seminar.

This comprehensive new resource focuses on applied electromagnetics and takes readers beyond the conventional theory with the use of contemporary mathematics to improve the practical use of electromagnetics in emerging areas of field communications, wireless power transfer, metamaterials, MIMO and direction-of-arrival systems. The book explores the existing and novel theories and principles of electromagnetics in order to help engineers analyze and design devices for today's applications in wireless power transfers, NFC, and metamaterials. This book is organized into clear and logical sections spanning from fundamental theory, to applications, promoting clear understanding through-out. This resource presents the theory of electromagnetic near fields including chapters on reactive energy, spatial and spectral theory, the scalar antenna, and the morphogenesis of electromagnetic radiation in the near field zone. The Antenna Current Green's Function Formalism is explored with an emphasis on the foundations, the organic interrelationships between the fundamental operational modes of general antenna systems, and the spectral approach to antenna-to-antenna interactions. The book offers perspective on nonlocal metamaterials, including the material response theory, the far-field theory, and the near-field theory.
