Book Description
La méthode TLM (Transmission Line Matrix) permet de résoudre un problème d'électromagnétisme et d'analyser le comportement de certains milieux. Il s'agit d'un outil performant qui bénéficie d'un développement important. Sa capacité à simuler avec précision des situations variées incluant des matériaux complexes est démontrée. Cet ouvrage en expose les bases théoriques et les principaux développements. La méthode historique en deux et trois dimensions et les dernières évolutions y sont détaillées pour aboutir aux noeuds sophistiqués les plus utilisés. Les simulations des milieux fermés et ouverts sont traitées et en particulier les frontières absorbantes (PML) pour les milieux ouverts. L'introduction d'éléments passifs ou actifs, la simulation de fils minces, la simulation des milieux dispersifs comme les plasmas ou les ferrites par l'utilisation de la transformée en Z sont étudiées.

Book Description
This book addresses recent developments in mathematical analysis and computational methods for solving direct and inverse problems for Maxwell’s equations in periodic structures. The fundamental importance of the fields is clear, since they are related to technology with significant applications in optics and electromagnetics. The book provides both introductory materials and in-depth discussion to the areas in diffractive optics that offer rich and challenging mathematical problems. It is also intended to convey up-to-date results to students and researchers in applied and computational mathematics, and engineering disciplines as well.

Book Description
Computational Electromagnetism refers to the modern concept of computer-aided analysis, and design, of virtually all electric devices such as motors, machines, transformers, etc., as well as of the equipment inthe currently booming field of telecommunications, such as antennas, radars, etc. The present book is uniquely written to enable the reader-- be it a student, a scientist, or a practitioner-- to successfully perform important simulation techniques and to design efficient computer software for electromagnetic device analysis. Numerous illustrations, solved exercises, original ideas, and an extensive and up-to-date bibliography make it a valuable reference for both experts and beginners in the field. A researcher and practitioner will find in it information rarely available in other sources, such as on symmetry, bilateral error bounds by complimentarity, edge and face elements, treatment of infinite domains, etc. At the same time, the book is a useful teaching tool for courses in computational techniques in certain fields of physics and electrical engineering. As a self-contained text, it presents an extensive coverage of the most important concepts from Maxwells equations to computer-solvable algebraic systems-- for both static, quasi-static, and harmonic high-frequency problems.BenefitsTo the EngineerA sound background necessary not only to understand the principles behind variational methods and finite elements, but also to design pertinent and well-structured software.To the Specialist in Numerical ModelingThe book offers new perspectives of practical importance on classical issues: the underlying symmetry of Maxwell equations, their interaction with other fields of physics in real-life modeling, the benefits of edge and face elements, approaches to error analysis, and "complementarity."To the TeacherAn expository strategy that will allow you to guide the student along a safe and easy route through otherwise difficult concepts: weak formulations and their relation to fundamental conservation principles of physics, functional spaces, Hilbert spaces, approximation principles, finite elements, and algorithms for solving linear systems. At a higher level, the book provides a concise and self-contained introduction to edge elements and their application to mathematical modeling of the basic electromagnetic phenomena, and static problems, such as eddy-current problems and microwaves in cavities.To the StudentSolved exercises, with "hint" and "full solution" sections, will both test and enhance the understanding of the material. Numerous illustrations will help in grasping difficult mathematical concepts.

Book Description
Au début du XXe siècle, la science semblait complète et les lois de la nature presque toutes découvertes, mais des chercheurs intrépides ont réveillé un géant endormi en découvrant la mécanique quantique. Dans le monde quantique, les objets peuvent se trouver en deux endroits à la fois, le voyage dans le temps est non seulement possible, mais nécessaire, la cause et l'effet peuvent s’inverser, et la simple observation d'un objet change son état. Des univers parallèles à l'antimatière, laissez-vous guider par le facétieux Tim James à la découverte des bizarreries du monde de l'infiniment petit !

Book Description
The book deals with formal aspects of electromagnetic theory from the classical, the semiclassical and the quantum viewpoints in essays written by internationally distinguished scholars from several countries. The fundamental basis of electromagnetic theory is examined in order to elucidate Maxwell's equations, identify problematic aspects as well as outstanding problems, suggest ways and means of overcoming the obstacles, and review existing literature.This book will be especially valuable for those who wish to go in depth, rather than simply use Maxwell's equations for the solution of engineering problems. Graduate students will find it rich in dissertation topics, and advanced researchers will relish the controversial and detailed arguments and models.

Book Description
Le chauffage par induction est actuellement absent dans beaucoup d'applications industrielles, et pourtant, il a une capacité importante d'innovations technologiques dès lors qu'un apport de chaleur est nécessaire. Cette absence vient du fait que les acteurs du chauffage par induction se sont intéressés essentiellement aux applications traditionnelles d'induction pour la fusion, l'élaboration et le traitement thermique des matériaux de bonnes conductivités électrique et thermique. L'objectif de cet ouvrage Électrothermie est donc de développer des méthodologies d'analyse et de la conception des systèmes du chauffage par induction pour les matériaux peu conducteurs. Dans ce cadre, les modèles analytiques et numériques couplés des phénomènes électromagnétiques et thermiques sont utilisés pour étudier et concevoir des installations du plasma inductif, de démontrer la faisabilité d'une technique du contrôle non destructif thermo inductive, et enfin illustrer les performance du chauffage par induction pour l'élaboration des matériaux composites à base de fibres de carbone.

Book Description
Seabed logging (SBL) gathers the electromagnetic methods of marine subsoil exploration and more specifically those dedicated to the exploration of oil and gas at sea. Appeared in 2000, these techniques, with more than 500 industrial jobs, present after 15 years of commercial success a discovery record rate of nearly 90 % and seem now to turn the world in the offshore exploration field. Proposing a serious index of the presence of hydrocarbons , electromagnetic SBL coupled with seismic reflection survey is probably the first reliable method for direct detection of hydrocarbons. Complementing the structural concepts of oil exploration used since the 1920s, the SBL now radically modifies the approach and the philosophies of exploration especially those then including drilling and well logging activities. Electromagnetic Seabed Logging: a new tool for oil and gas prospecting, which original publication in French was in 2012, presents these methods, its principles, advantages, limitations, instruments, modeling and applications. It is also designed to be a tool for a reflection on the use of electromagnetic energy for the exploration in a conductive medium as sea water thus setting the theoretical and practical limits of these investigations for future developments. This book is intended of course for the geophysicists and the petroleum geologists, but also for the earth scientists, the reservoir engineers and the log analysts
