Magnetic materials are currently the focus of a great deal of research activity. Their properties pose great intellectual challenges to physicists and chemists, and the increase of activity in this field is likely to continue with the arrival of third generation facilities such as the European Synchotron Radiation Facility and Advanced Light Source. This is the first book devoted to the use of x-ray beam techniques to study magnetic properties of materials, serving as an ideal reference source. It covers both experimental and theoretical issues in topics such as dichroism, elastic scattering,...

This textbook offers students and researchers an overview of the physical aspects of ferromagnetism. It emphasizes the explanations of physical concepts rather than rigorous theoretical treatments that require a more advanced background than is assumed here. The book includes recent developments and techniques in magnetics, and describes magnetic phenomena and engineering applications in magnetism.

This book is based on lecture notes for a graduate course that has been offered at University of Nebraska-Lincoln on and off since 1998. The course is intended to provide graduate students with the basic aspects of the continuum modeling of electroelastic interactions in solids. A concise treatment of linear, nonlinear, static and dynamic theories and problems is presented. The emphasis is on formulation and understanding of problems useful in device applications rather than solution techniques of mathematical problems. The mathematics used in the book is minimal. The book is suitable for a...

The rare earths play a unique role in science. These seventeen related elements afford a panoply of subtle variations deriving from the systematic development of their electronic configurations, allowing a test of theory with excellent resolution. In contrast they find widespread use in even the most mundane processes such as steel making, for polishing materials and gasoline cracking catalysts. In between are exotic uses such as TV screen phosphors, lasers, high strength permanent magnets and chemical probes.

This multi-volume handbook covers the entire rare earth field in an integrated...

A practical new approach that brings together circuit theory and field theory for the practicing engineer
To put it frankly, the traditional education of most engineers and scientists leaves them often unprepared to handle many of the practical problems they encounter. The Fields of Electronics: Understanding Electronics Using Basic Physics offers a highly original correction to this state of affairs.
Most engineers learn circuit theory and field theory separately. Electromagnetic field theory is an important part of basic physics, but because it is a very mathematical subject,...

This book will shape the course of electromagnetics research for decades to come. Fourteen leading researchers from five countries reveal their latest research results in detail and review parallel developments. The topics discussed, though unconventional today, are destined to attract great attention as shrinking device sizes make electromagnetic effects ever more important.

These topics include the rotation of polarization of electric waves by a twisted structure; homogenization of linear bianistotropic composite materials; novel free-space techniques to characterize complex...

The Keep It Simple (KISS) philosophy is the primary focus of this book. It is written in very simple language with minimal math, as a compilation of helpful EMI troubleshooting hints. Its light-hearted tone is at odds with the extreme seriousness of most engineering reference works that become boring after a few pages. This text tells engineers what to do and how to do it. Only a basic knowledge of math, electronics, and a basic understanding of EMI/EMC are necessary to understand the concepts and circuits described.

Once EMC troubleshooting is demystified, readers learn there are quick...

This third edition of the popular text, while retaining nearly all the material of the previous edition, incorporates material on important new developments in lasers and quantum electronics. The book covers phase-conjugate optics and its myriad applications, the long wavelength quaternary semiconductor laser, and our deepened understanding of the physics of semiconductor lasers - especially that applying to their current modulations and limiting bandwidth, laser arrays and the related concept of supermodes, quantum well semiconductor lasers, the role of phase amplitude coupling in laser...

This work provides a detailed introduction to the principles of Doppler and polarimetric radar, focusing in particular on their use in the analysis of weather systems. The authors first discuss underlying topics such as electromagnetic scattering, polarization, and wave propagation. They then detail the engineering aspects of pulsed Doppler polarimetric radar, before examining key applications in meteorology and remote sensing. The book is aimed at graduate students of electrical engineering and atmospheric science as well as practitioners involved in the applications of polarimetric radar.

This book is designed to give the student a fundamental, in-depth understanding of all the essential features of the magnetic recording process for both high density disk and tape recording. The book provides a thorough grounding in four basic areas of magnetic recording: structure and fields of heads and media, the replay process, the recording process, and medium noise analysis. Besides the fundamental issues, key systems questions of nonlinearities, overwrite, side track phenomena, error rate estimates as well as comparisons of MR and inductive heads will be discussed. The student will be...

This book provides an understanding of the theoretical foundations for the calculation of electromagnetic processes. Photon production processes are particularly important in astrophysics, since almost all of our knowledge of distant astronomical objects comes from the detection of radiation from these sources. Further, the conditions therein are extremely varied and a wide variety of naturally occurring electromagnetic phenomena can be described by limiting forms of the basic theory.

The first chapter reviews some basic principles that are the underpinnings for a general...

-Joseph F. Keithley, a modern pioneer of instrumentation, brings you a fascinating history of electrical measurement from the ancient Greeks to the inventors of the early twentieth century. Written in a direct and fluent style, the book illuminates the lives of the most significant inventors in the field, including George Simon Ohm, Andre Marie Ampere, and Jean Baptiste Fourier. Chapter by chapter, meet the inventors in their youth and discover the origins of their lifelong pursuits of electrical measurement. Not only will you find highlights of important technological contributions, you will...

Introduces the fundamental principles of electricity and magnetism and explores their widespread applications, from powering modern technology to driving much of the human body.

This text attempts to give the reader an understanding of the key developments in moment methods and the early history of this development. It provides over 45 key papers in the field, many of which are from non-IEEE sources.

For scientists, research engineers, physicists and postgraduate students, this work introduces the essential aspects of electromagnetic waves in chiral and bi-isotropic media, to give the practical working knowledge necessary for new application development. It includes sections on effective methods of measurement, how chiral and BI media affect electromagnetic fields and wave propagation, and how to apply the theory to basic problems in waveguide, antenna and scattering analysis.

The NATO Advanced Research Workshop Bianisotropics 2002 was held in th Marrakesh, Morocco, during 8-11 May 2002. This was the 9 International Conference on Electromagnetics of Complex Media, belonging to a series of meetings where the focus is on electromagnetics of chiral, bianisotropic, and other materials that may respond to electric and magnetic field excitations in special manner. The first of these meetings was held in Espoo, Finland (1993), and the following venues were Gomel, Belarus (1993), Perigueux, France (1994), State College, Pennsylvania, USA (1995), the rivers and channels...
