EN DIMENSION 2, L'ONDE DANS LE GUIDE FORME PAR LA FENTE, EST DECOMPOSEE EN DEUX COMPOSANTES DECOUPLEES. POUR CHACUNE D'ELLES NOUS DEMONTRONS UN RESULTAT ASYMPTOTIQUE POUR UNE FAIBLE LARGEUR DU GUIDE, DONT LES PAROIS SONT SUPPOSEES DE CLASSE C 2, PERMETTANT DE MODELISER - EU EGARD A LA PROPAGATION - CELUI-CI PAR UNE VARIETE DE DIMENSION 1. LE MEME PRINCIPE EST DEMONTRE MOYENNANT DES HYPOTHESES LEGEREMENT PLUS CONTRAIGNANTES POUR LES EQUATIONS DE MAXWELL, CE QUI PERMET DE MODELISER LA PROPAGATION DANS UN GUIDE DE DIMENSION 3 DE LARGEUR PETITE PAR UNE PROPAGATION SUR UNE SURFACE. L'ETUDE DU PROBLEME GLOBAL (COUPLAGE AVEC L'EXTERIEUR) EST POURSUIVIE EN DIMENSION 2 POUR UNE FENTE DE FAIBLE LARGEUR A PAROI SUFFISAMMENT REGULIERE. NOUS DEMONTRONS QUE LE SEUL CALCUL DE TROIS COEFFICIENTS DE COUPLAGE PERMET DE COMBINER DEUX METHODES TEMPORELLE PAR VOLUMES FINIS, L'UNE A L'EXTERIEUR DE LA FENTE, L'AUTRE A L'INTERIEUR DE CELLE-CI MODELISEE PAR UNE VARIETE DE DIMENSION 1, DE MANIERE A CALCULER LA PROPAGATION A TRAVERS LA FENTE. NOUS DONNONS UNE INTERPRETATION PHYSIQUE DE CES COEFFICIENTS, ET NOUS DEMONTRONS QU'ILS DEPENDENT PEU DE LA GEOMETRIE POUR UNE FENTE MINCE DE CLASSE C 2 ET DE LA FREQUENCE DU MOMENT QUE CELLE-CI RESTE EN-DESSOUS D'UNE CERTAINE VALEUR. DES RESULTATS NUMERIQUES PROBANTS DE LA VALIDITE ET DE L'EFFICACITE DE CETTE METHODE SONT PRESENTES. _ DANS LA SECONDE ETUDE NOUS DEMONTRONS UN RESULTAT DE PROPAGATION DES SINGULARITES EN ELASTODYNAMIQUE AVEC BORD LIBRE. CE RESULTAT PERMET D'ENONCER UN CRITERE SIMPLE CARACTERISANT L'EXISTENCE D'UN CONTROLE FRONTIERE DANS LE CAS GENERAL.

Available in PDF, EPUB and Kindle. Book excerpt: This book explores generalized Lorenz–Mie theories when the illuminating beam is an electromagnetic arbitrary shaped beam relying on the method of separation of variables. The new edition includes an additional chapter covering the latest advances in both research and applications, which are highly relevant for readers. Although it particularly focuses on the homogeneous sphere, the book also considers other regular particles. It discusses in detail the methods available for evaluating beam shape coefficients describing the illuminating beam. In addition it features applications used in many fields such as optical particle sizing and, more generally, optical particle characterization, morphology-dependent resonances and the mechanical effects of light for optical trapping, optical tweezers and optical stretchers. Furthermore, it provides various computer programs relevant to the content.

Book excerpt: Fractal structures or geometries currently play a key role in all models for natural and industrial processes that exhibit the formation of rough surfaces and interfaces. Computer simulations, analytical theories and experiments have led to significant advances in modeling these phenomena across wild media. Many problems coming from engineering, physics or biology are characterized by both the presence of different temporal and spatial scales and the presence of contacts among different components through (irregular) interfaces that often connect media with different characteristics. This work is devoted to collecting new results on fractal applications in engineering from both theoretical and numerical perspectives. The book is addressed to researchers in the field.

Available in PDF, EPUB and Kindle. Book excerpt: [Infotext]((Kurztext))These are the proceedings of the 7th International Conference on Hyperbolic Problems, held in Zürich in February 1998. The speakers and contributors have been rigorously selected and present the state of the art in this field. The articles, both theoretical and numerical, encompass a wide range of applications, such as nonlinear waves in solids, various computational fluid dynamics from small-scale combustion to relativistic astrophysical problems, multiphase phenomena and geometrical optics. ((Volltext))These proceedings contain, in two volumes, approximately one hundred papers presented at the conference on hyperbolic problems, which has focused to a large extent on the laws of nonlinear hyperbolic conservation. Two-fifths of the papers are devoted to mathematical aspects such as global existence, uniqueness, asymptotic behavior such as large time stability, stability and instabilities of waves and structures, various limits of the solution, the Riemann problem and so on. Roughly the same number of articles are devoted to numerical analysis, for example stability and convergence of numerical schemes, as well as schemes with special desired properties such as shock capturing, interface fitting and high-order approximations to multidimensional systems. The results in these contributions, both theoretical and numerical, encompass a wide range of applications such as nonlinear waves in solids, various computational fluid dynamics from small-scale combustion to relativistic astrophysical problems, multiphase phenomena and geometrical optics.

Book excerpt: Developed from a course taught to senior undergraduates, this book provides a unified introduction to Fourier analysis and special functions based on the Sturm-Liouville theory in L2. The text’s presentation follows a clear, rigorous mathematical style that is highly readable. The author first establishes the basic results of Sturm-Liouville theory and then provides examples and applications to illustrate the theory. The final two chapters, on Fourier and Laplace transformations, demonstrate the use of the Fourier series method for representing functions to integral representations.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the edited versions of the papers presented at the Second International Workshop on Electric and Magnetic Fields held at the Katholieke Universiteit van Leuven (Belgium) in May 1994. This Workshop deals with numerical solutions of electromagnetic problems in real life applications. The topics include coupled problems (thermal, mechanical, electric circuits), CAD & CAM applications, 3D eddy current and high frequency problems, optimisation and application oriented numerical problems. This workshop was organised jointly by the AIM (Association of Engineers graduated from de Montefiore Electrical Institute) together with the Departments of Electrical Engineering of the Katholieke Universiteit van Leuven (Prof. R. Belmans), the University of Gent (Prof. J. Melkebbek) and the University of Liege (Prof. W. Legros). These laboratories are working together in the framework of the Pole d'Attraction Interuniversitaire - Inter-University Attractie-Pole 51 - on electromagnetic systems led by the University of Liege and the research work they perform covers most of the topics of the Workshop. One of the principal aims of this Workshop was to provide a bridge between the electromagnetic device designers, mainly industrialists, and the electromagnetic field computation developers. Therefore, this book contains a continuous spectrum of papers from application of electromagnetic models in industrial design to presentation of new theoretical developments.

This book was released on 2012-05-01 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces graduate students and researchers in mathematics and the sciences to the multifaceted subject of the equations of hyperbolic type, which are used, in particular, to describe propagation of waves at finite speed. Among the topics carefully presented in the book are nonlinear geometric optics, the asymptotic analysis of short wavelength solutions, and nonlinear interaction of such waves. Studied in detail are the damping of waves, resonance, dispersive decay, and solutions to the compressible Euler equations with dense oscillations created by resonant interactions. Many fundamental results are presented for the first time in a textbook format. In addition to dense oscillations, these include the treatment of precise speed of propagation and the existence and stability questions for the three wave interaction equations. One of the strengths of this book is its careful motivation of ideas and proofs, showing how they evolve from related, simpler cases. This makes the book quite useful to both researchers and graduate students interested in hyperbolic partial differential equations. Numerous exercises encourage active participation of the reader. The author is a professor of mathematics at the University of Michigan. A recognized expert in partial differential equations, he has made important contributions to the transformation of three areas of hyperbolic partial differential equations: nonlinear microlocal analysis, the control of waves, and nonlinear geometric optics.
