This comprehensive new resource based on the classic Artech House title, Microwave Materials for Wireless Applications, introduces the use of new microwave materials for passive devices including ferrites, magnetization garnets, dielectric materials, and absorbers for wireless and antenna applications. This book explores a new set of magnetic and dielectric materials that assist with size reduction of passive devices such as ferrite isolators and circulators. Revised data on the applications of absorbers, including examples of different combinations of magnetic, dielectric, and absorber materials into integrated devices is presented. Meta-materials for antennas and potential antenna integration onto soft boards or LTCC filter technologies using tunable devices with new materials are covered. Professionals learn how new material designs use properties of certain ions in oxide compounds to reduce their physical size, including in cellular base stations designed for 4G and 5G cell phone communication systems. This book exhibits how the integration of new materials into cellular systems using common transmission lines will further save size and reduce complexity. New technologies are presented demonstrating the use of sol-gel processing and ceramic processing in the use of low temperature co-fired ceramics, plastic molding, and 3D printing demonstrating improved device designs.

This practical resource offers you an in-depth, up-to-date understanding of the use of microwave magnetic materials for cutting-edge wireless applications. The book discusses device applications used in wireless infrastructure base stations, point-to-point radio links, and a range of more specialized microwave systems. You find detailed discussions on the attributes of each family of magnetic materials with respect to specific wireless applications. Moreover, the book addresses two of the hottest topics in the field today OCo insertion loss and intermodulation. This comprehensive reference also covers ancillary materials that are used with microwave magnetic materials, such as dielectrics, absorbers, and conductors."

Solid State Materials have been gaining importance in recent times especially in the context of devices which can provide necessary infrastructure and flexibility for various human endeavours. In this context, microwave materials have a unique place especially in various device applications as well as in communication networks. Various technological developments are taking place in fine-tuning these materials for specific applicatio"ns and in fixed band frequencies. Though the science and technology of these materials has reached an advanced stage, systematic attempts are still lacking in bringing all available information in a single source. The present. volume is a modest attempt in this direction, though it cannot be considered to be the one that satisfies completely desired components and information required. The editors have enlisted certain articles of interest in this area, especially those dealing with measurement techniques, chapters dealing with materials like Ferrites, YIGs, Radome and high Tc superconducting materials which are of current interest. The editors are fully aware that the coverages are not comprehensive either in scope or in depth. The purpose of this volume is only to acquaint oneself of certain aspects of a fast developing field. The editors will be grateful for any comments or suggestions in this endeavour. V. R. K. MURTHY S. SUNDARAM B. VISWANATHAN Contents Preface v 1.

This book is devoted to the theoretical and experimental investigation of the optoelectronic oscillator (OEO) with direct and external modulation of laser emission. Such devices, sources of precision radio frequency oscillations using laser excitation, are novel and technologically relevant, with manifold possible applications. The book includes a review of the present state of the theory and generation techniques in microwave and mm-wave ranges for traditional and optoelectronic oscillators, description of OEO construction and operation principles, theoretical oscillation analysis and mathematical description of the relevant semi-classical laser physics, and investigation of the power spectral density of noises. Technical features and advantages of OEOs with external and direct modulation of laser emission are discussed together with functional diagrams. The characteristics of OEOs are compared with other traditional RF oscillators, such as quartz, surface acoustic waves, and oscillators with electromagnetic wave cavities. Special attention is paid to Q-factors and phase noises of RF carriers at small offsets. The authors discuss the technical characteristics of modern optoelectronic methods for precision RF oscillation formation, such as commercial large-dimension and compact quantum frequency standards with optical pumping on cesium and rubidium cells. This book is aimed at scientists and engineers in academia and industry who work with sources of microwave and mm-wave signals.
