Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Rotation rate sensors have important applications in navigation and guidance control systems. An investigation of magnetostatic surface waves (MSSW) in yttrium iron garnet (YIG) films on cylindrical surfaces was undertaken as a first step in fabricating a new type of rotation rate sensor recently proposed at AFCRL. The sensor employs magnetic (or acoustic) waves in a ring laser type configuration.

This book was released on 2013-11-21 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades, interest in the field of interaction of microwaves with ferrimagnetics has steadily increased. Investigations in tlris field have led to the development of a number of devices used for a variety of applications. The initial emphasis of the investigators was on the microwave behavior of ferrimagnetics placed in cavities and metallic waveguides and associated devices. This work has been presented in various books, monographs, and reviews written during the sixties. In recent years, interest in microwave propagation in ferrimagnetics has shifted from loaded waveguides to relatively new areas, e. g. , magnetostatic and magnetoelastic waves in layered structures, microwave propagation in ferrimagnetic strip lines and microstrips, etc. Such investigations are important from the viewpoint of devices such as delay lines, filters, convolvers, guided wave amplifiers, striplines, and microstrip phase shif ters, circulators, edge guided mode isolators, etc. As such, we feit the need for a text (meant for graduate students starting work in these areas as weil as practicing electrical engineers and applied physicists) which presents a coherent account of the various aspects of propagation of microwaves (electromagnetic as weil as magnetoelastic) in biased ferrimagnetics and discusses the relatively recent developments in the theory and operation of the aforementioned devices, and this book is the result. A biased ferrimagnetic is, in the mathematical sense, a complicated medium, electromagnetically as weil as elastically.
