Book Description
Waveguide Junction Circulators brings together for the first time all the design aspects of this class of device. In a typical application the circulator allows a single antenna to be used for both transmission and reception. Together with semiconductor, passive and electronic devices, the circulator constitutes an essential building block in modern radar, satellite and telecommunication equipment. Features include: * Examination of the properties and adjustments of the 3-port junction circulator and focus on the gyromagnetic resonator * Description of the design of practical classic circulator arrangements * Discussion of aspects of filter theory in the design of the classic 3-port junction circulator * Consideration of practical concerns such as insertion loss and commercial specifications Written by a leading academic authority and experienced industrial consultant, Waveguide Junction Circulators is a vital information source for designers working in microwave engineering. This valuable guide provides the academic researcher with a firm foundation in the theoretical aspects of this class of device whilst offering the industrial engineer an experimental platform for commercial design.

Book Description
Circulator design has advanced significantly since the first edition of this book was published 25 years ago. The objective of this second edition is to present theory, information, and design procedures that will enable microwave engineers and technicians to design and build circulators successfully. This resource contains a discussion of the various units used in the circulator design computations, as well as covers the theory of operation. This book presents numerous applications, giving microwave engineers new ideas about how to solve problems using circulators. Design examples are provided, which demonstrate how to apply the information to real-world design tasks.

Book Description
Discusses the fundamental principles of the design and development of microwave satellite switches utilized in military, commercial, space, and terrestrial communication This book deals with important RF/microwave components such as switches and phase shifters, which are relevant to many RF/microwave applications. It provides the reader with fundamental principles of the operation of some basic ferrite control devices and explains their system uses. This in-depth exploration begins by reviewing traditional nonreciprocal components, such as circulators, and then proceeds to discuss the most recent advances. This sequential approach connects theoretical and scientific characteristics of the devices listed in the title with practical understanding and implementation in the real world. Microwave Polarizers, Power Dividers, Phase Shifters, Circulators and Switches covers the full scope of the subject matter and serves as both an educational text and resource for practitioners. Among the many topics discussed are microwave switching, circular polarization, planar wye and equilateral triangle resonators, and many others. Translates concepts and ideas fundamental to scientific knowledge into a more visual description Describes a wide array of devices including waveguides, shifters, and circulators Covers the use of finite element algorithms in design Microwave Polarizers, Power Dividers, Phase Shifters, Circulators and Switches is an ideal reference for all practitioners and graduate students involved in this niche field.

Book Description
The feasibility of a symmetrical, high-power, four-port, waveguide, junction circulator for operation at S band was demonstrated. Both H-plane and E-plane configurations were studied. The ferrites utilized in the circulators were polycrystalline yttrium-iron-garnet (YIG) materials doped with gadolinium (Gd), aluminum (Al), and dysporosium (Dy) in various combinations. In addition, various loading techniques and metallic center posts were evaluated. Single- and double-disk geometries were used with a magnetizing field applied along the ferrite axis in each design. The H-plane configuration has an insertion loss slightly above 1.0 dB, is power-limited at approximately 600 kW peak, 600 watts average, is physically larger than the E-plane design, and requires a comparatively large biasing field. The E-plane configuration can handle a greater amount of power, is lighter and more compact, operates with a lower biasing field, and the insertion loss is approximately 0.5 dB. High-power operation at 1.0 MW peak, 1.0 kW average was achieved. (Author).

Book Description
MODERN FERRITES, Volume 2 A robust exploration of the basic principles of ferrimagnetic and their applications In Modern Ferrites: Volume 2, renowned researcher and educator, Vincent G. Harris delivers a comprehensive overview of ferrimagnetic phenomena and discussions of select applications of modern ferrite materials in emerging technologies and applications. Volume 2 explores fundamental properties of ferrite systems, including their structure, chemistry, and magnetism, as well as practical applications, such as permanent magnets; inductors, inverters, and filters; and their use in emerging applications as metamaterials, multiferroics, and biomedical technologies. In addition to the properties of ferrites, the included resources explore the processing, structure, and property relationships in ferrites as nanoparticles, thin and thick films, compacts, and crystals. The authors discuss how these relationships are key to realizing practical device applications laying the foundation for next generation communications, radar, sensing, and biomedical technologies. This volume includes: A comprehensive review of ferrite discoveries and impacts upon ancient cultures, their scientific evolution, and societal benefits; Discussion of the origins of magnetism in ferrimagnetic oxides including superexchange theory, GKA-rules, and recent developments in density functional theory; In-depth examination of ferrite power conversion and conditioning components and their processing as low temperature co-fired ceramics; Ferrite-based electromagnetic interference suppression and electromagnetic absorption; Nonlinear microwave devices; multiferroic and emerging magnetoelectric devices; Biomedical applications of ferrite nanoparticles Perfect for RF engineers and magnetitians working in the fields of RF electronics, radar, communications, and spintronics as well as other emerging technologies. Modern Ferrites will earn a place on the bookshelves of engineers and scientists interested in the ever-expanding technologies reliant upon ferrite materials and new processing methodologies. Modern Ferrites Volume 1: Basic Principles, Processing and Properties is also available (ISBN: 9781118971468).

Book Description
This book collects much of Helszajn's work (formerly, Heriot-Watt University) and includes closed-form and finite element calculations of the propagation constant, attenuation and mode spectrum for the ridge waveguide, and power-current and power-voltage definitions of impedance. Circular polarization is also treated. Propagation properties where the waveguide has a dielectric filler are calculated. The treatment is then extended to more complex designs, including quadruple ridge waveguides with and without a gyromagnetic filler. The text includes descriptions of many of the passive devices which can be realized using these waveguides, including isolators, phase shifters, and circulators. c. Book News Inc.
