This book was released on 2001 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface acoustic wave (SAW) devices are recognized for their versatility and efficiency in controlling and processing electrical signals. This has resulted in a multitude of device concepts for a wide range of signal processing functions, such as delay lines, filters, resonators, pulse compressors, convolvers, and many more. As SAW technology has found its way into mass market products such as TV receivers, pagers, keyless entry systems and cellular phones, the production volume has risen to millions of devices produced every day. At the other end of the scale, these are specialized high performance signal processing SAW devices for satellite communication and military applications, such as radar and electronic warfare. This volume, together with Volume 1, presents an overview of recent advances in SAW technology, systems and applications by some of the foremost researchers in this exciting field.

Download or read book Acousto Optic Interaction in Surface Acoustic Waves and Its Application to Real Time Signal Processing written by D. Schumer and published by . This book was released on 1977 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of the interaction of coherent light with surface acoustic waves and an experimental demonstration of the application of the interaction to new devices are presented. The analysis, based upon classical electromagnetic theory and a phenomenological formulation of the photoelastic effect, is applied to the piezoelectric material LiNbO3, and provides good agreement with previously published experimental data. Explicit account is taken of the linear electro-optic and linear elasto-optic contributions to the interaction. The experimental demonstration of applications is restricted to the side-entry technique, an interaction configuration providing the longest interaction length between a surface acoustic wave and unguided optical wave. The relative merits of this configuration are discussed. New experimental results for the real-time side-entry convolver employing optical heterodyning include autocorrelation of Barker codes, ambiguity function generation, demonstration of a parallel acoustic track geometry to inhibit reflections, and measurement of diffraction characteristics for polarized light. Results are given for the correlation of a time varying light intensity distribution with an electrical signal, and the application to an optical communication system is indicated. The scanning of one and two dimensional black and white transparencies is performed, and the extension to color image scanning is demonstrated. All experiments are performed using Y-cut Z-propagating LiNbO3. Acoustic frequencies employed range from 45 MHz to 100 MHz. Laser sources are HeNe and Ar. Devices are analyzed and discussed with reference to the diffraction integral of scalar diffraction theory.

This book was released on 1977 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of illumination with bandgap light on the convolution of surface acoustic waves on ZnO and GaAs has been investigated as a function of light wavelength and crystal temperature. The experiments indicate that the photoenhancement effect in ZnO is sensitive to trapping and surface preparation. A possible model for the dependence of photoenhancement on photon wavelength in ZnO has been proposed. Attempts to observe the photoenhancement effect in GaAs were unsuccessful because of problems in obtaining the correct sample resistivity. (Author).

Download or read book Acousto optic Interactions written by and published by . This book was released on 1976 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: New devices are described which are based on optical waveguides on lithium niobate crystals, using the material anisotropy, including couplers, electro-optic modulator and light multiplexer, and optical deflector and scanner using collinear acousto-optic interaction between surface acoustic waves and optical surface waves. Complete theory for the propagating modes and coupled modes is presented. A new type of waveguide is presented for use with surface acoustic wave devices for real-time direct scanning and Fourier transform scanning of optical images, which introduces no additional transmission loss over that for unguided propagation. Test pattern results demonstrate the ability of this type of waveguiding to increase the transverse resolution of such scanners, and good correlation between theoretical and experimental results is shown.

This book was released on 2010-09-08 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid growth of the mobile communication market has triggered extensive research on the bulk as well as surface acoustic wave devices in the last decade. Quite a few important results on the modeling and simulation of Film Bulk Acoustic Resonator (FBAR) and Layered SAW devices were reported recently. The other recent advance of acoustic waves in solids is the so-called phononic crystals or phononic band-gap materials. Analogous to the band-gap of light in photonic crystals, acoustic waves in periodic elastic structures also exhibit band-gap. Important applications of phononic band gap materials can potentially be found with creating a vibration free environment in microstructures, and design of advanced acoustic frequency filter, etc. In addition to the wave electronics and phononic crystals, to facilitate the emerging needs in the quantitative nondestructive evaluation of materials, waves in anisotropic solids and/or electro-, magneto- interaction problems also regained much attention recently. Topics treated include: Waves in piezoelectric crystals; Simulation of advanced BAW and SAW devices; Analysis of band gaps in phononic structures; Experimental investigation of phononic structures; Waves in multilayered media;Waves in anisotropic solids and/or electro-, magneto- interaction problems.
