Nombre d’idées fausses circulent sur les effets des rayonnements non ionisants sur notre santé. Elles conduisent à une simplification excessive, à des amalgames fâcheux ou à une analyse parfois orientée des données. Les effets peuvent être alors exagérés ou plus grave, minimisés. Les auteurs de cet ouvrage (médecins, ingénieurs ou chercheurs) se sont attachés à fournir au public une information scientifique validée, facilement compréhensible et raisonnée sur les champs électromagnétiques et leurs effets biologiques et sanitaires. Après un rappel général sur la physique des ondes et une présentation des rayonnements non ionisants, les auteurs font le point sur les principales sources d’émission rencontrées dans un environnement quotidien. Ils résument simplement, mais le plus fidèlement possible les connaissances actuelles sur leurs effets biologiques et les limites d’exposition recommandées par les organismes internationaux pour pouvoir les utiliser en sécurité. Conçu comme un livre à tiroirs, chacun pourra s’immerger en fonction de sa curiosité et de son niveau de connaissances. Ce n’est ni un catalogue exhaustif de toutes les études faites à ce jour, ni une réduction de l’état des connaissances à quelques études choisies. L’objectif n’est pas non plus de présenter toutes les sources de rayonnements non ionisants. Le lecteur intéressé pourra s’il le souhaite, approfondir ses connaissances en consultant les sélections bibliographiques présentées par les auteurs à la fin de chaque chapitre.

Public concern over possible health effects from electromagnetic fields (EMF) has led to the preparation of this handbook. Potential risks of EMF exposure from facilities such as power lines or mobile phone base stations present a difficult set of challenges for decision-makers. The challenges include determining if there is a hazard from EMF exposure and what the potential health impact is. Responding to these challenges requires the involvement of individuals or organizations with the right set of competencies, combining relevant scientific expertise, strong communication skills and good jud

Providing the latest developments in the application of electromagnetic methods, this title is a revised edition of the book "Frequency and Transient Soundings" by A.A. Kaufman and G.V. Keller published in 1983. In this volume the physical principles, theory and interpretation of electromagnetic soundings and profiling are developed and explained. The authors systematically derive the relationships between components of electromagnetic fields measured, transmitter-receiver separations and frequency spectrum on the one hand, and parameters of geoelectric sections on the other hand. In addition you will find case histories illustrating the applications of modern instruments for electromagnetic soundings and profiling in agricultural and geotechnical engineering, environmental site assessments and ground water investigations.

Electrophoresis is defined as the transport of electrically charged particles in a direct current electric field. Electrophoresis has been around for more than a century as a phenomenon in electrokinetics. Field effect electroosmosis is a novel phenomenon in electrokinetics that adds a new dimension in capillary electrophoresis. In this book, field effect electroosmosis is introduced, and a beautiful spectrum of applications of electrophoresis was presented.

The topics of anisotropy and bianisotropy are fundamental to electromagnetics from both theoretical and experimental perspectives. These properties underlie a host of complex and exotic electromagnetic phenomena in naturally occurring materials and in relativistic scenarios, as well as in artificially produced metamaterials. As a unique guide to this rapidly developing field, the book provides a unified presentation of key classic and recent results on the stsudies of constitutive relations, spacetime symmetries, planewave propagation, dyadic Green functions, and homogenization of composite materials. The book offers an up-to-date extension to standard treatments of crystal optics with coverage on both linear and weakly nonlinear regimes.

This book is dedicated to the interaction of electromagnetic wave radiation in matter, such as the wave propagation in a plasmonic and conductive state, that are dispersive media. The different measurement methods of electrical properties of soils have been studied using several applications. The experimental results of the thermoelectric properties of a chalcogenide system and the electrical conductivity of molten salts and ionic conduction in electrolyte solutions are discussed. The application of an electric field impulse and its influence on the immune responses of animals by increasing different elements of the immune response is discussed. The electromagnetic radiation transmission through skin samples of pigs of different ages have been measured in order to understand the process of absorption and conversion. The methods and results are covered in the book.
