Blurb

Magnetoelectronics of Microwaves and Extremely High Frequencies in Ferrite Films, by Alexander A. Ignatiev of Saratov State University in Russia, offers a very detailed and specialized account of a new direction of magnetoelectronics of millimetric waves in the layered structures containing epitaxial ferrite films. The new electrodynamic approach for research of electromagnetic waves in layered bigyrotropic structures - excitation of waves in converters with parallel and orthogonal orientations - is thoroughly discussed.

The book is divided into three parts

- theory of electromagnetic wave excitation in multilayer bigyrotropic structures

- studies of electromagnetic wave excitation in film ferrite structures

- methods and devices for high-frequency parameter control of ferrite films

This book is intended for post-graduate students and researchers in the field of radiophysics and magnetoelectronics of millimetric waves, as well as those specializing in device design using ferrites.
