Book Description
Magnetostatic waves (MSWs) in magnetodielectric media are fundamental for the creation of various highly efficient devices for analog information processing in the microwave range. These devices include various filters, delay lines, phase shifters, frequency converters, nonreciprocal and nonlinear devices, and others. Magnetostatic Waves in Inhomogeneous Fields examines magnetostatic waves and their distribution in non-uniformly magnetized films and structures. The propagation of magnetostatic waves in magnetodielectric environments is accompanied by numerous and very diverse physical effects, sharply distinguishing them from ordinary electromagnetic waves in isotropic media. The authors address dispersion properties and noncollinearity of phase and group velocity vectors, as well as non-reciprocal propagation. Key Features Offers mathematical tools used in the calculation of properties of magnetostatic waves Includes a current literature review of magnetostatic waves and domain structures in garnet–ferrite films Considers the issue of converting magnetostatic waves into electromagnetic ones

Book Description
Magnetic materials can support propagating waves of magnetization; since these are oscillations in the magnetostatic properties of the material, they are called magnetostatic waves (sometimes "magnons" or "magnetic polarons"). Under the proper circumstances these waves can exhibit, for example, either dispersive or nondispersive, isotropic or anisotropic propagation, nonreciprocity, frequency-selective nonlinearities, soliton propagation, and chaotic behavior. This rich variety of behavior has led to a number of proposed applications in microwave and optical signal processing. This textbook begins by discussing the basic physics of magnetism in magnetic insulators and the propagation of electromagnetic waves in anisotropic dispersive media. It then treats magnetostatic modes, describing how the modes are excited, how they propagate, and how they interact with light. There are problems at the end of each chapter; many of these serve to expand or explain the material in the text. To enhance the book's usefulness as a reference, the answers are given for many of the problems. The bibliographies for each chapter give an entry to the research literature. Magnetostatic Waves will thus serve not only as an introduction to an active area of research, but also as a handy reference for workers in the field.

Book Description
Microwave properties of magnetostatic surface waves in saturated ferrimagnets are described. Particular emphasis is given to experimental aspects of the subject. A summary background is given of pertinent experimental investigations of magnetostatic surface waves (MSSW) from 1968, when they were first observed, to the present. Certain features such as nonreciprocity, electronic tunability, and high coupling efficiencies are discussed. Propagation losses, between 4 and 15 GHz, on chemically-polished yttrium iron garnet (YIG) slabs were measured. Effects of inhomogeneous internal fields, the effects of placing metal conducting planes parallel to the surface upon which the waves propagate to modify the dispersion relation, and the effects of surrounding a single crystal slab (supporting resonant modes) with metal coated polycrystalline YIG to increase field homogeneity, are considered. Magnetostatic surface wave losses, above a few GHz, are less than those of acoustic surface waves. It is concluded that MSSW technology complements ASW technology at high frequencies.

Book Description
This book presents recent scientific achievements in the investigation of magnetization dynamics in confined magnetic systems. Introduced by Bloch as plane waves of magnetization in unconfined ferromagnets, spin waves currently play an important role for description of very small systems.Spin wave confinement effect was experimentally discovered in the 1990s in permalloy microstripes. The diversity of systems where this effect is observed has been steadily growing since then, most of which will be addressed in this book. The book includes six chapters which originate from different groups of experimentalists and theoreticians dominating the field since the discovery of the effect. Different chapters of the book reflect different facets of spin wave confinement, providing a comprehensive description of the effect and its place in modern magnetism. It will be of value for scientists and engineers working on magnetic storage elements and magnetic logic, and is also suitable as an advanced textbook for graduate students.
