Basic Electromagnetic Theory (Essentials of Physics Series)
Basic Electromagnetic Theory is designed as a concise introduction to electromagnetic field theory emphasizing the physical foundations of the subject. It is aimed at both undergraduates and interested laypersons. It has been based on the authors experience both as a former field theorist (working on quantum electrodynamics) and currently as an applied optical physicist. As such, it covers much material from the standard university syllabus. it also develops a number of themes in greater detail, so as to cover a number of non-standard topics that provide a fuller understanding of the subject. A key aspect to the book is the macroscopic approach to the subject from the outset. Most readers will have some familiarity with the standard mathematics employed, but a review chapter is provided at the beginning to help give some guidance on these topics as they are used throughout the book.

For junior/senior-level electricity and magnetism courses. This book is known for its clear, concise, and accessible coverage of standard topics in a logical and pedagogically sound order. The highly polished Fourth Edition features a clear, easy-to-understand treatment of the fundamentals of electromagnetic theory, providing a sound platform for the exploration of related applications (AC circuits, antennas, transmission lines, plasmas, optics, etc.). Its lean and focused approach employs numerous new examples and problems.
The science of magnetically confined plasmas covers the entire spectrum of physics from classical and relativistic electrodynamics to quantum mechanics. During the last sixty years of research, our initial primitive understanding of plasma physics has made impressive progress thanks to a variety of experiments – from tabletop devices with plasma temperatures of a few thousands of degrees and confinement times of less than 100 microseconds, to large tokamaks with plasma temperatures of up to five hundred million degrees and confinement times approaching one second. We discovered that plasma confinement is impaired by a variety of instabilities leading to turbulent processes with scales ranging from the plasma size to a few millimeters. Understanding these phenomena, which have slowed down progress towards a fusion reactor, requires the use of very sophisticated diagnostic tools, many of which employ electromagnetic waves. The primary objective of this book is to discuss the fundamental physics upon which the application of electromagnetic waves to the study of magnetically confined plasmas is based.
Cutnell and Johnson has been the #1 text in the algebra-based physics market for almost 20 years. PHYSICS 9e continues that tradition by providing superior support students need to facilitate a deeper level of conceptual understanding, improve their reasoning skills and see the relevance of physics to their lives and future careers. Research studies have shown that there is a strong correlation between time on task and student learning gains. PHYSICS 9e with WileyPLUS offers instructors innovative new tools for engaging students. Through the use of a proven pedagogy that includes integrated reading activities, instructors are able to much more effectively monitor student reading and progress, resulting in a higher level of student engagement with the course content. Success in physics is also based on practice. Working high quality problem sets is one of the best ways for students to learn physics. However, to get the greatest benefit from working problems students need immediate feedback and expert coaching. PHYSICS 9e with WileyPLUS offers an extensive and tested set of assessment questions and sophisticated wrong answer feedback. Access to WileyPLUS not included with this textbook. This text features: • Tools that help students develop a conceptual understanding of physics: Conceptual Examples, Concepts & Calculations, Focus on Concepts homework material, Check Your Understanding questions, Concept Simulations (an online feature), Concepts at a Glance (available on the instructor companion site). • Features that help students improve their ability to reason in an organized and mathematically correct manner: Explicit reasoning steps in all examples, Reasoning Strategies for solving certain classes of problems, Analyzing Multiple-Concept Problems, homework problems with associated Guided Online (GO) Tutorials, Interactive LearningWare (an online feature), Interactive Solutions (an online features) • Examples that show students the relevance of physics to their lives: a wide range of applications from everyday physics to modern technology to biomedical applications. There is extensive support for premed and biomedical students including biomedical applications in the text and end of chapter problems marked with a caduceus, practice MCAT exams, and a supplemental book of biomedical applications.
Power electronics is an enabling technology for almost all electrical applications. The field is growing rapidly because electrical devices need electronic circuits to process their energy. Elements of Power Electronic, the first book to discuss this subject in a conceptual framework, provides comprehensive coverage of power electronics at a level suitable for novices in the field. It aims to establish a fundamental engineering basis for power electronics analysis, design, and implementation. More than 160 examples and 350 chapter problems support the presented concepts. An extensive World Wide Web site http://power.ece.uiuc.edu/krein text includes additional examples, laboratory materials, and author contact.
