Book Synopsis Diffraction par des surfaces rugueuses by : Kofi Sényo Edee
Download or read book Diffraction par des surfaces rugueuses written by Kofi Sényo Edee and published by . This book was released on 2003 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nous présentons un modèle théorique et numérique pour simuler la diffraction d'ondes électromagnétiques par des surfaces rugueuses monodimensionnelles et non périodiques. La méthode d'étude consiste à écrire et à résoudre les équations de Maxwell en coordonnées de translation afin de faciliter l'écriture des conditions aux limites. Dans un premier chapitre, la méthode est appliquée à l'étude théorique de la diffraction d'une onde plane par un plan localement déformé diélectrique ou conducteur. Les équations de Maxwell, écrite dans le système de coordonnées de translation sont résolues dans l'espace de Fourier par une méthode des moments avec comme fonctions de base des sinus cardinaux et des distributions de Dirac pour fonction test. On obtient une équation aux valeurs propres et les solutions propres servent à la représentation du champ. Dans le second chapitre, une étude numérique est développée, afin de cerner les limites de la méthode. Premièrement, une étude numérique de la stabilité et de la convergence de la méthode en fonction des différents paramètres est effectuée. Deuxièmement, une réflexion sur la représentation du champ lointain et proche conduit à coupler le modèle avec le théorème d'extinction. Le phénomème de faible couplage en champs lointain est abordé à la fin de ce chapitre, dans le but d'étendre le modèle à des surfaces de grande étendue spatiale. Le troisième et dernier chapitre présente une extension du modèle au cas de l'incidence conique et d'un faisceau d'ondes planes. Les applications numériques sont effecutuées sur des surfaces rugueuses aléatoires suivant une statistique Gaussienne

Book Synopsis Acoustic Waves in Periodic Structures, Metamaterials, and Porous Media by : Noé Jiménez
Download or read book Acoustic Waves in Periodic Structures, Metamaterials, and Porous Media written by Noé Jiménez and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delivers a comprehensive and up-to-date treatment of practical applications of metamaterials, structured media, and conventional porous materials. With increasing levels of urbanization, a growing demand for motorized transport, and inefficient urban planning, environmental noise exposure is rapidly becoming a pressing societal and health concern. Phononic and sonic crystals, acoustic metamaterials, and metasurfaces can revolutionize noise and vibration control and, in many cases, replace traditional porous materials for these applications. In this collection of contributed chapters, a group of international researchers reviews the essentials of acoustic wave propagation in metamaterials and porous absorbers with viscothermal losses, as well as the most recent advances in the design of acoustic metamaterial absorbers. The book features a detailed theoretical introduction describing commonly used modelling techniques such as plane wave expansion, multiple scattering theory, and the transfer matrix method. The following chapters give a detailed consideration of acoustic wave propagation in viscothermal fluids and porous media, and the extension of this theory to non-local models for fluid saturated metamaterials, along with a description of the relevant numerical methods. Finally, the book reviews a range of practical industrial applications, making it especially attractive as a white book targeted at the building, automotive, and aeronautic industries.

Book Synopsis The Language of Physics by : Elizabeth Garber
Download or read book The Language of Physics written by Elizabeth Garber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is the first explicit examination of the key role that mathematics has played in the development of theoretical physics and will undoubtedly challenge the more conventional accounts of its historical development. Although mathematics has long been regarded as the "language" of physics, the connections between these independent disciplines have been far more complex and intimate than previous narratives have shown. The author convincingly demonstrates that practices, methods, and language shaped the development of the field, and are a key to understanding the mergence of the modern academic discipline. Mathematicians and physicists, as well as historians of both disciplines, will find this provocative work of great interest.

Book Synopsis Molecular Beam Epitaxy by : John Wilfred Orton
Download or read book Molecular Beam Epitaxy written by John Wilfred Orton and published by . This book was released on 2015 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a history of Molecular Beam Epitaxy (MBE) as applied to the growth of semiconductor thin films (note that it does not cover the subject of metal thin films). It begins by examining the origins of MBE, first of all looking at the nature of molecular beams and considering their application to fundamental physics, to the development of nuclear magnetic resonance and to the invention of the microwave MASER. It shows how molecular beams of silane (SiH4) were used to study the nucleation of silicon films on a silicon substrate and how such studies were extended to compound semiconductors such as GaAs. From such surface studies in ultra-high vacuum the technique developed into a method of growing high quality single crystal films of a wide range of semiconductors. Comparing this with earlier evaporation methods of deposition and with other epitaxial deposition methods such as liquid phase and vapour phase epitaxy (LPE and VPE). The text describes the development of MBE machines from the early 'home-made' variety to that of commercial equipment and show how MBE was gradually refined to produce high quality films with atomic dimensions. This was much aided by the use of various in-situ surface analysis techniques, such as reflection high energy electron diffraction (RHEED) and mass spectrometry, a feature unique to MBE. It looks at various modified versions of the basic MBE process, then proceed to describe their application to the growth of so-called 'low-dimensional structures' (LDS) based on ultra-thin heterostructure films with thickness of order a few molecular monolayers. Further chapters cover the growth of a wide range of different compounds and describe their application to fundamental physics and to the fabrication of electronic and opto-electronic devices. The authors study the historical development of all these aspects and emphasise both the (often unexpected) manner of their discovery and development and the unique features which MBE brings to the growth of extremely complex structures with monolayer accuracy.
Book Synopsis Acoustical Analysis of the Tanpura by : Asoke Kumar Datta
Download or read book Acoustical Analysis of the Tanpura written by Asoke Kumar Datta and published by Springer. This book was released on 2018-10-01 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the acoustic signal analysis and spectral dynamics of the tanpura, an Indian plucked string instrument. In addition, it strives to provide a logical and objective explanation of Indian classical musicians’ cognitive experience. Issues of relevance in this regard include the rich, mellifluous sound; the undulation of the loudness; the somewhat cyclical variation of the timbre, which is strongly related to these undulations; and the occasional perception of virtual notes to which no strings are tuned. The book analyses the materials used in the tanpura, the instrument’s simple structure, the intricacies of the lower bridge, and the theory of string vibration with variable string length. Cognitive experiments to provide the basis for perceptual quality assessment, as well as a methodology for ranking, are described. This is followed by acoustic analyses, both temporal and spectral, for sounds produced by male and female tanpuras, for each individual string and the combined one. An important aspect related to the naturalness of perceived sound, namely the intrinsically associated random perturbations, is also discussed. The apparent irregularities perceived in the acoustic signal produced by the tanpura reveal the importance of examining the signal from the perspective of non-linear analysis, an aspect that is also covered in the book. Given its scope, the book will appeal to students and researchers in the fields of music acoustics, artificial intelligence, and cognitive science, as well as musicians and musicologists around the world.
