Tuneable Film Bulk Acoustic Wave Resonators by Spartak Gevorgian,Alexander Tagantsev,Andrei K Vorobiev Pdf

To handle many standards and ever increasing bandwidth requirements, large number of filters and switches are used in transceivers of modern wireless communications systems. It makes the cost, performance, form factor, and power consumption of these systems, including cellular phones, critical issues. At present, the fixed frequency filter banks based on Film Bulk Acoustic Resonators (FBAR) are regarded as one of the most promising technologies to address performance -form factor-cost issues. Even though the FBARs improve the overall performances the complexity of these systems remains high. Attempts are being made to exclude some of the filters by bringing the digital signal processing (including channel selection) as close to the antennas as possible. However handling the increased interference levels is unrealistic for low-cost battery operated radios. Replacing fixed frequency filter banks by one tuneable filter is the most desired and widely considered scenario. As an example, development of the software based cognitive radios is largely hindered by the lack of adequate agile components, first of all tuneable filters. In this sense the electrically switchable and tuneable FBARs are the most promising components to address the complex cost-performance issues in agile microwave transceivers, smart wireless sensor networks etc. Tuneable Film Bulk Acoustic Wave Resonators discusses FBAR need, physics, designs, modelling, fabrication and applications. Tuning of the resonant frequency of the FBARs is considered. Switchable and tuneable FBARs based on electric field induced piezoelectric effect in paraelectric phase ferroelectrics are covered. The resonance of these resonators may be electrically switched on and off and tuned without hysteresis. The book is aimed at microwave and sensor specialists in the industry and graduate students. Readers will learn about principles of operation and possibilities of the switchable and tuneable FBARs, and will be given general guidelines for designing, fabrication and applications of these devices.

Modeling and Measurement Methods for Acoustic Waves and for Acoustic Microdevices by Marco G. Beghi Pdf

Acoustics is a mature field which enjoys a never ending youth. New developments are induced by either the search for a better understanding, or by technological innovations. Micro-fabrication techniques introduced a whole new class of microdevices, which exploit acoustic waves for various tasks, and in particular for information processing and for sensing purposes. Performance improvements are achievable by better modelling tools, able to deal with more complex configurations, and by more refined techniques of fabrication and of integration in technological systems, like wireless communications. Several chapters of this book deal with modelling and fabrication techniques for microdevices, including unconventional phenomena and configurations. But this is far from exhausting the research lines in acoustics. Theoretical analyses and modelling techniques are presented, for phenomena ranging from the detection of cracks to the acoustics of the oceans. Measurement methods are also discussed, which probe by acoustic waves the properties of widely different systems.

Solid Acoustic Waves And Vibration: Theory And Applications by Li-feng Ge Pdf

Solid Acoustic Waves and Vibration: Theory and Applications is an exciting new book that takes readers inside a fascinating subject. It is charming that there is a complex and delicate structure in characteristic values, which is revealed by introducing a conceptual system including space operator, space-time variable, reference Poisson's ratio, etc., and developing the analytical models for all limiting cases. The dispersion curves of waves in an elastic plate are determined completely, and a systematic and concise description of the fundamental theory of this subject is given.As MEMS and NEMS technology develops, a number of new issues presents, such as the effects of residual stress, thin-film, air captured in micro-air-gaps and coating on the system, which make the problem complicated and spark debates. Micro-diaphragms are modeled by a plate in tension and mounted on air-spring, a general TDK equation of vibration of plates, including free, forced and damped vibrations, and its solutions are developed. The loading effect of coating is modeled by a mass load; a micro-load theory is presented. This book is a summary of the author's long-term research on electromechanical transducers and these related issues, and they provide an excellent description combining theory and application. The principle of electromechanical transducers, which achieve the conversion between mechanical and electrical energy, occupying a particularly important position in the field of robotics and intelligent machines, is elucidated by introducing the concepts of space-time operator, complex transformation factor, inversion impedance, etc., and an unfiled equivalent circuit is presented. The applications in micromachined capacitive ultrasonic transducers (mCUTs, CMUTs) for biomedical imaging and ultrasonic mass resonators (mUMRs) for biochemical sensing, including plate-type, beam-type, nanowire, bulk-wave, LAW and SAW delay-line ultrasonic resonators are described. This interdisciplinary book will be increasingly attractive as MEMS and NEMS technology develops.
