Available in PDF, EPUB and Kindle. Book excerpt: The report contains a detailed description of diffraction in acoustic surface wave devices. This source of loss is highly important in the design and realization of bandpass filters, long time delay lines and other devices for electronic sensors and communications systems. A complete review of acoustic surface wave diffraction on anisotropic substrates is presented. Full experimental verification of theory is provided. Complete computer program listings and descriptions are provided. The limits of applicability of the parabolic velocity surface theory are quantitatively delineated. Universal diffraction loss design curves are given for all parabolic materials. A limitation in the use of the exact angular spectrum of waves theory occurs for materials having a power flow angle slope approximately - 1 unless the velocity surfaces are very accurately known. Both YZ LiNbO3 and 16-1/2 degree double rotated LiNbO3 fall in this category. Approximate diffraction loss design curves are given for YZ LiNbO3. A complete tabular summary of all important material properties affecting acoustic surface wave device design is included. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Surface Acoustic Wave Filters gives the fundamental principles and device design techniques for surface acoustic wave filters. It covers the devices in widespread use today: bandpass and pulse compression filters, correlators and non-linear convolvers and resonators. The newest technologies for low bandpass filters are fully covered such as unidirectional transducers, resonators in impedance element filters, resonators in double-mode surface acoustic wave filters and transverse-coupled resonators using waveguides. The book covers the theory of acoustic wave physics, the piezoelectric effect, electrostatics at a surface, effective permittivity, piezoelectric SAW excitation and reception, and the SAW element factor. These are the main requirements for developing quasi-static theory, which gives a basis for the non-reflective transducers in transversal bandpass filters and interdigital pulse compression filters. It is also needed for the reflective transducers used in the newer devices. A thorough revision of a classic on surface acoustic wave filters first published in 1985 and still in print Uniquely combines easy-to-understand principles with practical design techniques for all the devices in widespread use today Complete coverage of all the latest devices which are key to mobile phones, TVs and radar systems Includes a new foreword by Sir Eric Albert Ash

Book excerpt: Physical Acoustics: Principles and Methods, Volume XIII is a six-chapter text that covers a variety of topics in physical acoustics, including the principles of ultrasonic waves, plate modes, diffraction, mode vibrators, ray theory, and acoustic emission. Chapter 1 deals with the theory and application of anelasticity in studying various types of relaxations, such as point defect, grain-boundary, thermoelastic, phonon and electron relaxations, and magnetic relaxations. Chapter 2 presents the different methods used in studying the very important Type II superconductor materials. Chapter 3 surveys the plate modes in surface acoustic wave devices and the theory needed to understand plate modes in piezoelectric media, as well as to eliminate or reduce their effect on the response. Chapter 4 tackles the ways of predicting diffraction loss and phase distortion, and discusses the alleviation of diffraction effects by acoustic beam shaping, material selection and orientation, and alterations in the transducer structure. Chapter 5 examines plate vibrators whose thickness direction has an arbitrary crystallographic orientation and the tools for the analysis of the properties of doubly rotated cuts, with special emphasis on such cuts in quartz, berlinite, lithium tantalate, and lithium niobate. Chapter 6 discusses generalized ray theory and transient responses of layered elastic solids. This book will be of great value to researchers in the fields of electronics technology and applied and engineering mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: Research on ferroelectricity and ferroelectric materials started in 1920 with the discovery by Valasek that the variation of spontaneous polarization in Rochelle salt with sign and magnitude of an applied electric field traced a complete and reproducible hysteresis loop. Activity in the field was sporadic until 1935, when Busch and co-workers announced the observation of similar behavior in potassium dihydrogen phosphate and related compounds. Progress thereafter continued at a modest level with the undertaking of some theoretical as well as further experimental studies. In 1944, von Hippel and co-workers discovered ferroelectricity in barium titanate. The technological importance of ceramic barium titanate and other perovskites led to an upsurge of interest, with many new ferroelectrics being identified in the following decade. By 1967, about 2000 papers on various aspects of ferroelectricity had been published. The bulk of this widely dispersed literature was concerned with the experimental measurement of dielectric, crystallographic, thermal, electromechanical, elastic, optical, and magnetic properties. A critical and excellently organized cpmpilation based on these data appeared in 1969 with the publica tion of Landolt-Bornstein, Volume 111/3. This superb tabulation gave instant access to the results in the literature on nearly 450 pure substances and solid solutions of ferroelectric and antiferroelectric materials. Continuing interest in ferroelectrics, spurred by the growing importance of electrooptic crystals, resulted in the publication of almost as many additional papers by the end of 1969 as had been surveyed in Landolt-Bornstein.

Book excerpt: Surface Acoustic Wave Devices and Their Signal Processing Applications is a textbook that combines experiment and theory in assessing the signal processing applications of surface acoustic wave (SAW) devices. The operating principles of SAW devices are described from a circuit design viewpoint. This book is comprised of 18 chapters and begins with a historical background on surface acoustic waves and a discussion on the merits of SAW devices as well as their applications. The next chapter introduces the reader to the basics of acoustic waves and piezoelectricity, together with the effect of acoustic bulk waves on the performance of SAW filters. The principles of linear phase SAW filter design and equivalent circuit models for a SAW filter are then described. The remaining chapters focus on trade-offs in linear phase SAW filter design; compensation for second-order effects; harmonic SAW delay lines for gigahertz frequencies; and coding techniques using linear SAW transducers. The final chapter highlights Some other significant alternative design techniques and applications for SAW devices. This monograph will be suitable for engineering or physics students as well as engineers, scientists, and technical staff in industry who seek further information on SAW-based circuits, systems, and applications.
