The topic of surface waves lies at the interface between a number of disci plines - physics, theoretical and applied mechanics, electroacoustics, ap plied mathematics, surface science and seismology. This volume, based on papers delivered at European Mechanics Colloquium 226, reflects this diversity in approach and background, while showing strong links between phenomena arising from different fields. The emphasis is on recent de velopments such as nonlinear and other nonclassical effects,which have great importance for both pure science and for applications such as signal processing, nondestructive evaluation and seismic studies. In recent years there has been considerable progress in the mathe matical treatment of nonlinear effects, of viscoelastic and of more novel constitutive effects which modify the predictions of linear elastic and piezo electric theory for surface acoustic wave (SAW) propagation. A number of these themes serve to group the contents of this volume. Part I contains recent advances in the rigorous mathematical treatment of nonlinearity, together with a paper giving experimental results showing the need for further theoretical development. Part II deals with anisotropic elasticity, showing that even the linear theory presents many possible behaviours, which are still not fully categorized.

The most important results of surface wave scattering by local defects such as grooves, random roughness, elastic wedges are given. Different theoretical approaches and practical rules for solving the surface wave problems are presented.

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. Contents: Coupling-of-Modes Analysis of SAW Devices (V Plessky & J Koskela); Theory and Applications of Green''s Functions (A R Baghai-Wadji); New Piezoelectric Substrates for SAW Devices (J Kosinski); Pseudo and High Velocity Pseudo SAWs (M P da Cunha); SAW Devices Beyond 5 GHz (H Odagawa & K Yamanouchi); Wireless SAW Identification and Sensor Systems (F Schmidt & G Scholl); Interaction of Surface Acoustic Waves, Electrons, and Light (A Wixforth). Readership: Graduate students, researchers and academics in device and circuit design, as well as designers of mobile communications systems.

Aerodynamics is a branch of fluid mechanics that deals with the motion of air and other gaseous fluids and the forces acting on bodies in motion relative to such fluids. Aerodynamics are classified according to Mach number into incompressible subsonic, compressible subsonic, transonic, supersonic and hypersonic aerodynamics. Aerodynamics can be divided into different forms of internal or external aerodynamics. For example, the study of flow properties inside a gas turbine or rocket engine is an example of internal aerodynamics that is important in accurately estimating thrust force. Examples of external aerodynamics include the flow around the body of airplanes, helicopters, space capsules, cars, rockets and missiles, trains, ships, wind turbines, and even such structures as bridges and tall buildings, which often have to withstand strong winds. Since the first human flights until today, aerodynamics has been growing and developing rapidly. Aerodynamics is one of the applied sciences in engineering that pursues several goals such as estimating forces, moments on objects moving in the air, or estimating heat transfer from these objects. Aerodynamics investigates how gases interact with moving bodies. The main purpose of aerodynamics in most cases is to reduce drag forces and increase lift force, which can lead to less fuel consumption in vehicles and achieving the greatest speed. Of course, in some special cases, such as hypersonic aerodynamics, there is a greater interest in increasing drag to reduce the adverse effects of aerodynamic heating. Another goal of studying aerodynamics is to obtain the details of the flow around flying objects. For example, the correct operation of a control rudder or flap in a supersonic aircraft, or the recognition of the phenomenon of blackout during spacecraft reentry, which occurs under the influence of aerothermodynamic heating and plasma formed around the antenna, is of great importance.

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.

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.
