Available in PDF, EPUB and Kindle. Book excerpt: This book discusses various approaches of the active research going on in the field of acoustic waves. The concept of acoustic wave is an extensive one; it materializes in a variety of mediums, from solids to plasmas, and at varying length and time scales which range from sub-micrometric layers in microdevices to seismic waves in the Sun's interior. Theoretical attempts lead to a comprehensive understanding of this phenomenon. Such waves are useful in exploring the characteristics of a variety of structures, be it inorganic layers and/or other bio-structures. These waves can also function as a tool to influence matter, from the gentle evaporation of bio-molecules to be evaluated, to the phase conversions inferred by intense shock waves. Furthermore, a whole class of widespread micro tools, inclusive of filters and sensors, depends upon the behavior of these waves propagating in fine layers. The book highlights acoustic waves as manipulative tools and as microdevices.

Download or read book Solid Acoustic Waves And Vibration Theory And Applications written by Li-feng Ge and published by World Scientific. This book was released on 2021-09-23 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...

Download or read book Seismic Applications of Acoustic Reciprocity written by J.T. Fokkema and published by Elsevier. This book was released on 2013-10-22 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seismic applications of the reciprocity theorem developed in this book are partly based on lecture notes and publications from Professor de Hoop. Every student Professor de Hoop has taught knows the egg-shaped figure (affectionately known as "de Hoop's egg") that plays such an important role in his theoretical description of acoustic, electromagnetic and elastodynamic wave phenomena. On the one hand this figure represents the domain for the application of a reciprocity theorem in the analysis of a wavefield and on the other hand it symbolizes the power of a consistent wavefield description of this theorem. The roots of the reciprocity theorem lie in Green's theorem for Laplace's equation and Helmholtz's extension to the wave equation. In 1894, J.W. Strutt, who later became Lord Rayleigh, introduced in his book The Theory of Sound this extension under the name of Helmholtz's theorem. Nowadays it is known as Rayleigh's reciprocity theorem. Progress in seismic data processing requires the knowledge of all the theoretical aspects of the acoustic wave theory. The reciprocity theorem was chosen as the central theme of this book as it constitutes the fundaments of the seismic wave theory. In essence, two states are distinguished in this theorem. These can be completely different, although sharing the same time-invariant domain of application, and they are related via an interaction quantity. The particular choice of the two states determines the acoustic application, in turn making it possible to formulate the seismic experiment in terms of a geological system response to a known source function. In linear system theory, it is well known that the response to a known input function can be written as an integral representation where the impulse response acts as a kernel and operates on the input function. Due to the temporal invariance of the system, this integral representation is of the convolution type. In seismics, the temporal behaviour of the system is dealt with in a similar fashion; however the spatial interaction needs a different approach. The reciprocity theorem handles this interaction by identifying one state with the spatial impulse function, also known as the Green's function, while the other state is connected with the actual source distribution. In general, the resulting integral representation is not a spatial convolution. Moreover, the systematic use of the reciprocity theorem leads to a hierarchical description of the seismic experiment in terms of increasing complexity. Also from an educational point of view this approach provides a hierarchy and the student learns to break down the seismic problem into constituent partial solutions. This book should contribute to the understanding that the reciprocity theorem is a powerful tool in the analysis of the seismic experiment.

Download or read book Bulk and Surface Acoustic Waves written by Guigen Zhang and published by CRC Press. This book was released on 2022-01-27 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces acoustic wave theories using a reader-friendly matrix-based linear algebra approach. It will enable the reader to take advantage of software tools such as MATLAB (commercial codes) and OCTAVE (open-source codes) to gain better and deeper understanding of the underlying physics quickly. In this aspect, this text can be regarded as a practical introduction of the acoustic wave theories in an easy-to-follow linear algebra format using matrix manipulations instead of an abstract approach relying on tensor manipulations. The book also uses case studies to demonstrate how the fundamentals on acoustic waves discussed throughout the book are applied in device designs and analyses such that the connections and interdependences between the underlying sciences and the observed behavior and performances can be better appreciated by the reader. To achieve this, all problems for illustrations, examples, case studies, and device analyses are developed and solved based on the mathematical foundations laid out in the book.

Download or read book Fundamentals and Applications of Acoustic Metamaterials written by Vicente Romero-Garcia and published by John Wiley & Sons. This book was released on 2019-08-09 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few decades, metamaterials have revolutionized the ways in which waves are controlled, and applied in physics and practical situations. The extraordinary properties of metamaterials, such as their locally resonant structure with deep subwavelength band gaps and their ranges of frequency where propagation is impossible, have opened the way to a host of applications that were previously unavailable. Acoustic metamaterials have been able to replace traditional treatments in several sectors, due to their better performance in targeted and tunable frequency ranges with strongly reduced dimensions. This is a training book composed of nine chapters written by experts in the field, giving a broad overview of acoustic metamaterials and their uses. The book is divided into three parts, covering the state-of-the-art, the fundamentals and the real-life applications of acoustic metamaterials.

Download or read book Ultrasound written by M.H. Repacholi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures presented at the International School of Radiation Damage and Protection at the "Ettore Majorana" Centre for Sci entific Culture in Erice, Italy, September 6-15, 1985. The sixth course of the School, entitled "Advances in Applications, Biological Effects, and Dosimetry of Ultrasound," provided an in-depth review of all facets of ultra sound interactions and their biological effects on living systems, allowing an assessment of the hazard potential of the various applications of ultra sound. Particular reference was made to possible health risks associated with medical ultrasound exposure since this use is by far the most prevalent. Since the initial application of ultrasound to submarine detection, medical diagnostic and therapeutic applications have become predominant over the past 20 years. The question of safety of this physical agent is an extremely important one. In many industrialized countries most pregnant women receive at least one diagnostic ultrasound examination before the birth of the child. Thus, potential hazards to the fetus are of prime concern. This problem has been aggravated by the fact that the medical diagnostic applications of ultrasound have far outpaced research efforts on biological effects. A further compounding factor of concern to clinicians and scientists has been the use of higher and higher intensities by the manufacturers of ultrasound equipment, particularly higher peak pulse intensities.
