´By the end of the astonishing E=mc2 , a dedicated reader will have achieved, if only by osmosis, an understanding of Einstein´s theory of relativity and feel quite at ease dining with Nobel Prize winners. It´s a lucid, even thrilling study: the very best kind of science journalism. I didn´t know I could know so much.´ Fay Weldon, Books of the Year, Washington Post In 1905, Albert Einstein produced five historic papers that shattered many cherished scientific beliefs. One of those papers introduced the theory of special relativity and his legendary equation, E=mc2. Generations have grown up knowing that equation changed the shape of our world, but without understanding what it really means and why it is so significant. In this fascinating biography David Bodanis tells the story of one of the greatest scientific discoveries in history. He looks at the elements ´e´, ´m´ and ´c´; and honours the scientists whose landmark discoveries paved the way for Einstein. He plots the course of the equation through the twentieth century, showing how our lives have been revolutionized by its applications; and looks far ahead to the future. But as with any biography, it is the human stories that really ignite the subject - stories of love, courage and tragedy, of near misses, disappointments and disasters that, brought together by Bodanis in this remarkable book, turn Einstein´s seemingly impenetrable theory into a dramatic and accessible human achievement. ´ Both informative and highly readable...E=mc2 is a wonderful romp through Einstein´s famous formula.. this is everything a popular science book should be´ DAILY EXPRESS ´Bodanis himself seems like an intellectual thermonuclear explosion, a kind of Jonathan Miller on speed...This is an outstanding introduction to relativity by a gifted practitioner of popular science´ INDEPENDENT ´ With skill and plenty of colourful anecdotes Bodanis traces the intellectual ancestry of E=mc2...fast moving and entertaining´ THE TIMES ´E=mc2 reveals, amongst other wonders, how many women physicists were involved in the story. Which makes this morally improving, as well as fascinating reading´ George Walden, Books of the Year, SUNDAY TELEGRAPH ´The book fizzes in the readers imagination´ TIMES EDUCATIONAL SUPPLEMENT

The application of computational electromagnetics to real-world EMI/EMC engineering is an emerging technology. With the advancement in electronics, EMI/EMC issues have greatly increased in complexity. As a result, it is no longer possible to rely exclusively on traditional techniques and expect cost-effective solutions. The first edition of this book introduced computational electromagnetics to EMI/EMC engineering. This second edition continues the introduction of computational electromagnetics to EMI/EMC engineering, but also adds new modeling techniques, namely the Partial Element Equivalent Circuit method and the Transmission Line Matrix method, and updates to the science of EMI/EMC modeling that have occurred since the first edition was published. This book combines the essential elements of electromagnetic theory, computational techniques, and EMI/EMC engineering as they apply to computational modeling for EMI/EMC applications. It is intended to provide an understanding for those interested in incorporating modeling techniques in their work. A variety of modeling techniques are needed for anyone interested in using computational modeling in the real world. This book includes an introduction of all the popular modeling techniques, such as the Finite-Difference Time-Domain method, the Method of Moments, the Finite Element Method, the Partial Element Equivalent Circuit method and the Transmission Line Matrix method. EMI/EMC Computational Modeling Handbook, Second Edition will serve many different levels of readers. It will serve as a basic introduction to modeling as applied to EMI/EMC problems for the engineer interested in getting started, and it will help the person already using modeling as a tool to become more effective in using different modeling techniques. It will also be useful for the engineer who is familiar with computational techniques and wishes to apply them to EMI/EMC applications. This book can also be used as a text to help students of electromagnetic theory and application better understand real-world challenges facing engineers.
A comprehensive reference on state-of-the-art EMC modeling. The problems of electromagnetic interference are as old as radio wave communication. Only recently, however, has progress in numerical computation permitted the creation of models that help explain the physical phenomena of EM interference and predict and mitigate their effects. These models also invite an approach to solving EMC problems that furthers an understanding of underlying principles. EMC Analysis Methods and Computational Models provides detailed descriptions of the formulation, development, analysis, and use of EMC models. Departing from the rules-of-thumb approach for predicting electromagnetic interference, this book covers every step in the development of computational models--from the electromagnetic topology of the system to the development of coupling, penetration, and propagation models that describe the behavior of energy within the system. Supported by numerous illustrations, it * Covers circuit theory, low-frequency coupling, discrete source radiation, transmission line propagation, EM field penetration through apertures, diffusion, and shielding. * Discusses the approximations necessary in model development and contrasts approximate models with more rigorous models. * Includes exercises that elaborate the theory behind the models and indicate practical applications. * Provides computer programs based on models developed in the text. For practicing engineers, researchers, and graduate students, this book broadens the base of knowledge about the principles of EMC and lays the foundation for future research in the field.
Environmental electromagnetic pollution has drastically increased over the last decades. The omnipresence of communication systems, various electronic appliances and the use of ever increasing frequencies, all contribute to a noisy electromagnetic environment which acts detrimentally on sensitive electronic equipment. Integrated circuits must be able to operate satisfactorily while cohabiting harmoniously in the same appliance, and not generate intolerable levels of electromagnetic emission, while maintaining a sound immunity to potential electromagnetic disturbances: analog integrated circuits are in particular more easily disturbed than their digital counterparts, since they don´t have the benefit of dealing with predefined levels ensuring an innate immunity to disturbances. In addition, as different electronic systems are compactly integrated in the same apparatus, the parasitic electromagnetic coupling between these circuits sharing the same signal, power and ground lines, is a critical design parameter that can no longer be safely excluded from a product design flow: as an example, Bluetooth, GSM and WiFi services have to coexist and operate in harmony within the crammed confinement of a modern mobile phone. The objective of the research domain presented in EMC of Analog Integrated Circuits is to improve the electromagnetic immunity of considered analog integrated circuits, so that they start to fail at relevantly higher conduction levels than before.
