This book was released on 2014-06-05 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, first published in 2002, discusses challenges facing the implementation of an affordable tunable RF and microwave device technology. Low cost, tunable, microwave devices will have a tremendous impact on a variety of commercial and military systems, including tunable band-select filters for wireless communications, phase shifters and true time-delay devices for electronic scanning antennas, tunable radiating structures for frequency hopping, and tunable transformers to reduce RF impedance mismatch. Papers address topics from materials issues through devices and even a system-level demonstration of electronic beam steering. Specific materials issues discussed include: new tunable materials; issues of tunability, preparation and optimization of bulk and thin-film properties; materials, surface, and interface characterization; evaluation of material loss and loss mechanisms; effects of microstructure; and temperature stability. Phase shifters are featured and a new device concept for variable true time delay versus phase shift is introduced. A paraelectric lens is used to demonstrate electronic beam steering of an antenna at 10 GHz with about 2 dB of loss.

Book Synopsis Molecularly Imprinted Materials--sensors and Other Devices by : Kenneth J. Shea
Download or read book Molecularly Imprinted Materials--sensors and Other Devices written by Kenneth J. Shea and published by . This book was released on 2002 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of two symposia held at the 2002 MRS Spring Meeting in San Francisco. Molecular imprinting (MI) technology has attracted much attention and enjoyed tremendous development over the past decade. MI technology enables the preparation of materials with host sites that recognize specific guest molecules, analogous to the "lock-and-key" paradigm of antibodies and enzymes. Advantages of molecularly imprinted materials include: a degree of specificity approaching that of antibodies but with much greater temporal and thermal stability; rapid development because precise molecular design and chemical synthesis are unnecessary; and wide applicability because materials may be imprinted with almost any shape-persistent analyte of interest. Papers from Symposium M, "Molecularly Imprinted Materials, focus primarily on the fabrication of functional materials and devices based on MI materials. Studies are presented not only by experts in MI, but more importantly, by materials scientists integrating molecular imprinting with cutting-edge techniques in microfabrication and nanotechnology.

Book Synopsis Modeling and Numerical Simulation of Materials Behavior and Evolution: Volume 731 by : Antonios Zavaliangos
Download or read book Modeling and Numerical Simulation of Materials Behavior and Evolution: Volume 731 written by Antonios Zavaliangos and published by . This book was released on 2002-08-09 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, numerical simulation and modeling of materials coupling multiple-length scales has received much attention. While challenges remain, significant advances have been made. An equally important area of materials modeling, one that has received much less attention, is the integration of multiple physical phenomena for simulation of complex materials behavior. This volume offers a review of current capabilities in materials modeling and simulation that (1) bridge length scales and time scales and (2) couple a variety of physical phenomena to either provide insight into fundamental aspects of materials structure or predict materials behavior. By bringing together the materials modeling community from around the world, the volume provides a current snapshot of the field. Topics include: multiscale modeling; mechanical properties; transport phenomena; phase transformations; microstructure and its evolution; atomistic modeling; and materials structure and properties.

Book Synopsis Perovskite Materials by : Renata M. Wentzcovitch
Download or read book Perovskite Materials written by Renata M. Wentzcovitch and published by . This book was released on 2002 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perovskites form a large class of materials, deceptively simple in basic structure but immensely complex in compositional variations, symmetry changes, and physical properties. They include ferroelectrics, magnetoresistive materials, oxide ion and proton conductors, superconductors, and an abundant phase in the Earth's lower mantle. This volume brings together researchers operating in diverse areas with the common goal of understanding perovskite's intrinsic and extrinsic properties and their potential use. A recurring theme is the interplay of theory and experiment in understanding and predicting properties. Sessions on theory and modeling are featured, emphasizing phase changes and elasticity of Earth materials such as MgSiO3, and CaSiO3, and underscoring new magnetic and ferroelectric materials, including thin films and multilayers. These are complemented by experimental studies of the synthesis of new families of perovskites and property measurements. The volume shows the diversity of materials, measurements, and ideas being studied at present.
Book Synopsis Three-Dimensional Nanoengineered Assemblies: Volume 739 by : T. M. Orlando
Download or read book Three-Dimensional Nanoengineered Assemblies: Volume 739 written by T. M. Orlando and published by . This book was released on 2003-06-13 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in nanoscale materials processing are taking place at a rapid pace via myriad paths, including lithography, production of nanoparticle assemblies, surface manipulation and many others. Several of the techniques create structures that are three-dimensional or quasi three-dimensional. Even smaller structures intended to be two-dimensional have a 'more' three-dimensional geometry as their two-dimensional feature size and layer thickness become similar. The properties of these denser assemblies are driving different applications in electronics (single-electron devices), optics (photonic crystals and switches) and elsewhere. This 2003 book provides a venue for a productive scientific and technical exchange. The result is a compilation of papers which address fundamental studies, technological advances and novel approaches to developing and processing three-dimensional nanoscale assemblies. Topics include: nanofabrication via lithographic techniques; unconventional fabrication methods of nano-structures; physics, chemistry and modeling of nanostructures; fabrication and properties of 1D nanostructures; fabrication and properties of 3D nanostructures; applications of nanostructures and devices.
Book Synopsis Structure-Property Relationships of Oxide Surfaces and Interfaces II: Volume 751 by : Materials Research Society. Meeting
Download or read book Structure-Property Relationships of Oxide Surfaces and Interfaces II: Volume 751 written by Materials Research Society. Meeting and published by . This book was released on 2003-05-21 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because surfaces and interfaces found in oxide systems are strikingly complex, they can only be fully understood when examined at an atomic level. Yet for the materials scientist, such understanding is of paramount importance since future technological advances require it. This book, the second in a new series from the Materials Research Society, addresses structure-property relationships in these systems. Compared to the first proceedings, here we see a shift towards less well-defined materials that often more closely resemble reality, and an increasing effort to study these phenomena using in situ techniques. Of particular interest are discussions on the dynamical evolution of surface structure and relationships between the structure of surfaces, their stoichiometry and the distribution of bulk dislocations, which in turn can control the growth and retraction of islands and pits. Modeling and characterization of thin intergranular films, with a focus on how these films influence the properties of so many ceramic materials, are also addressed.
