Magnetic and Electric Resonance


Book Description

This book is devoted to a quasi-classical treatment of quantum transitions, with an emphasis on nuclear magnetic resonance, nuclear quadrupole resonance and electric dipolar resonance. The method described here is based on the quasi-classical description of condensed matter, and makes use of the equation of motion of harmonic oscillators with external forces. In addition to known results in magnetic resonance, the book also presents parametric resonance for electric dipoles and dipolar interaction which may lead to spontaneous electric polarization.




Wireless Power Transfer


Book Description

This book describes systematically wireless power transfer technology using magnetic resonant coupling and electric resonant coupling and presents the latest theoretical and phenomenological approaches to its practical implementation, operation and its applications. It also discusses the difference between electromagnetic induction and magnetic resonant coupling, the characteristics of various types of resonant circuit topologies and the unique features of magnetic resonant coupling methods. Designed to be self-contained, this richly illustrated book is a valuable resource for a broad readership, from researchers to engineers and anyone interested in cutting-edge technologies in wireless power transfer.













Relaxation in Magnetic Resonance


Book Description

Relaxation in Magnetic Resonance contains a series of lecture notes for a special topics course at the University of South Carolina in 1967. This book contains 21 chapters that summarize the main theoretical formulations and experimental results of magnetic resonance relaxation phenomena in several physical systems. This text deals first with the various methods in determining the relaxation behavior of the macroscopic spin system, such as Bloch equations, saturation methods, and transient resonant absorption. The subsequent chapters discuss the homogeneous and inhomogeneous resonant lines in solids and liquids and the significance of the Kubo-Tomita and Redfield theories in magnetic resonance. This book then considers the background research on electron spin resonance and relaxation in ionic solids. The concluding chapters explore the acoustic absorption coefficient and dielectric constant calculation; the relaxation processes in paramagnetic substance; and the characteristics of Mössbauer spectra and their application in magnetic relaxation. This book will be useful to both graduate students embarking upon thesis problems in relaxation and more advanced workers who seek an overall summary of the status of the field, as well as to physicists and chemists.







Principles of Magnetic Resonance


Book Description

It is a source of great pleasure to help launch the new Springer Series in Solid-State Sciences. Some years aga I wrote my book, Principles of Magnetic Resonance. I have been eager to publish a new book concerned with spin temperature, double resonance, and spin-flip line narrowing, topics basic to important trends in present-day magnetic resonance which were not treated in my earlier book. Invitations to lecture in Osaka, Japan, in Leuven, Belgium, and Lausanne, Switzerland, had provided occasion to prepare first drafts of the new topics and to get student feedback. My plans were changed, however, when I learned that Principles of M agnetic Resonance was no longer available. Dr. Lotsch, Physics Editor of Springer-Verlag, and I decided it made sense to combine the new book with a modified old one, thereby continuing to make available a complete text in basic magnetic resonance written with a philosophy of presenting a thorough treatment of a small number of concepts which are key to large areas of magnetic res on an ce. In addition to adding three new chapters, I have added new material to the original chapters, have added two new appendices-one on the use of Bloch equations to describe rate processes, the other on the effect of diffusion on spin echoes-and have augmented the collection of homework problems.
