Book excerpt: Composites of BSTO combined with other non electrically active oxides have demonstrated adjustable electronic properties which can be tailored for use in various electronic devices. These novel composites of barium strontium titanate (BSTO) and Oxide III compounds have already exhibited promising results in their ceramic form. The additive oxides modify the dielectric constant, tunability (change in the dielectric constant with applied voltage), and dielectric loss of the material. One application has been for use in phased array antennas and insertion has been accomplished into several working antenna systems. To further accommodate the frequencies required by these phased array antennas, thin films of the composites have been fabricated. Preliminary studies have indicated that thin films of such composites exhibit similar behavior as their bulk ceramic counterparts. The purpose of this study is to investigate the properties of the BSTO/Oxide III based compounds in thin film form. (MM).

Download or read book Frontiers of Engineering written by National Academy of Engineering and published by National Academies Press. This book was released on 1997-03-07 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space may have been called the "final frontier," but there are new frontiers to discover every day and engineers are the ones exploring them. Through groundbreaking research and cutting-edge technologies, engineers are now able to go beyond traditional boundaries, doing things that would have been all but impossible just a few short years ago. A sample of these exciting frontiers is revealed in this new publication from the National Academy of Engineering, which looks at new and emerging technologies to explain how they were developed and what new benefits they will bring. The book also highlights the kinds of pioneering research and technological work being done by some of the country's emerging leaders in engineering. Topics covered include microelectromechanical systems, design research, computer-generated visualization for design and display, and innovations in materials and processes.

This book was released on 1994 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: A ceramic ferroelectric phase shifting device has been demonstrated using Ba(1-x)Sr(x)TiO3 (BSTO) ceramics. As a part of an effort to optimize the electronic device performance in the phase shifter, various composites of BSTO combined with other nonelectrically active oxide ceramics have been formulated. In general, the composites have reduced dielectric constants, epsilon', where epsilon = epsilon' = i(epsilon)', and loss tangents, tan delta. The low dielectric constant and low loss tangent reduce the overall impedance mismatch and the insertion loss of the device, In addition, the overall tunability, change in the dielectric constant with applied voltage, is maintained at a relatively high level. The combination of electronic properties of these materials offer substantially higher operating frequencies, 10 GHz and above. Another application for one of the composites is for use as a capacitor-varistor surge protector. The microstructures including grain size and phase analysis have been examined using SEM and X-ray diffraction. The analysis of the phase formation, compositional variations, and grain size will be related to the electronic properties of the materials. (jg).
