Available in PDF, EPUB and Kindle. Book excerpt: Dispersive delay lines are a very stable and reliable pulse compression technique. As a result of increased requirements placed on pulse compression systems such as bandwidth, and time-bandwidth products, dispersive delay line techniques must be improved. Improved dispersive delay line technology as applied to pulse compression systems was investigated. Higher frequency of operation, broader bandwidth and greater ease of fabrication were the primary areas of interest. Two dispersive delay line configurations were investigated. The first configuration was a technique based on the dispersive characteristic which results from elastic waves propagating in thin metal strips, and the second configuration was based on slow wave propagation in a yttrium iron garnet. An investigation was undertaken to determine a highly efficient transducer to be used in conjunction with the dispersive delay lines. Vacuum deposited cadmium sulfide transducers proved to be most desirable and successful in constructing delay lines of broad instantaneous bandwidth. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Theoretical and experimental analyses and evaluations of transducers, delay media, and various techniques required to determine the feasibility of a configuration-dispersive delay line are presented. The delay line under study involved a new method of obtaining high-compression ratios and broad bandwidths with microwave acoustic techniques. No presently available materials were found which are suited for the delay medium. (Author).

This book was released on 2013-11-11 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some years ago it was not uncommon for materials scientists, even within the electronics industry, to work relatively independently of device engi neers. Neither group had a means to determine whether or not the materials had been optimized for application in specific device structures. This mode of operation is no longer desirable or possible. The introduction of a new material, or a new form of a well known material, now requires a close collaborative effort between individuals who represent the disciplines of materials preparation, materials characterization, device design and pro cessing, and the analysis of the device operation to establish relationships between device performance and the materials properties. The develop ment of devices in heteroepitaxial thin films has advanced to the present state specifically through the unusually close and active interchange among individuals with the appropriate backgrounds. We find no book available which brings together a description of these diverse disciplines needed for the development of such a materials-device technology. Therefore, the authors of this book, who have worked in close collaboration for a number of years, were motivated to collect their experiences in this volume. Over the years there has been a logical flow of activity beginning with heteroepi taxial silicon and progressing through the III-V and II-VI compounds. For each material the early emphasis on material preparation and characteriza tion later shifted to an emphasis on the analysis of the device characteristics specific to the materials involved.

MESHCHANOV, Kirill V. ZAICHENKO and published by Bentham Science Publishers. This book was released on 2024-02-09 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive book covers spectral analysis theory for radio signals and innovative devices designed for filtering electromagnetic waves across diverse frequency ranges. The book features 14 chapters that explain the working of devices utilizing surface and bulk acoustic waves. The chapters provide insights into acousto-optical and acousto-electronic Fourier processors' design principles, description methods, and characteristics. The inclusion of algorithms for multi-channel frequency discriminators enhances the precision of radio signal frequency measurements, ensuring stability in tracking frequency meters amidst intense interference. The book also includes mathematical modeling and experimental studies of waveguide microwave filters and X-band multiplexers, specifically tailored for non-pressurized radio electronic equipment in space communication systems. Notably, the book introduces readers to a compelling alternative to conventional filters: 2-D periodic structures in the form of thin perforated metal meshes that offer compact solutions for millimeter and sub-millimeter wave systems. A significant portion of the book is dedicated to the development of highly selective microstrip filters, incorporating complex topological structures with limited resonators and numerous couplings. This approach allows for the formation of numerous attenuation poles at finite frequencies, facilitating the achievement of high electrical parameters and compact filter sizes. Engineers and scientists specializing in communication systems design and analog Fourier processors will find a wealth of well-established and original solutions within this book.
