This book integrates concepts from physical acoustics with those from linear viscoelasticity and fractional linear viscoelasticity. Compressional waves and shear waves in applications such as medical ultrasound, elastography, and sediment acoustics often follow power law attenuation and dispersion laws that cannot be described with classical viscous and relaxation models. This is accompanied by temporal power laws rather than the temporal exponential responses of classical models. The book starts by reformulating the classical models of acoustics in terms of standard models from linear elasticity. Then, non-classical loss models that follow power laws and which are expressed via convolution models and fractional derivatives are covered in depth. In addition, parallels are drawn to electromagnetic waves in complex dielectric media. The book also contains historical vignettes and important side notes about the validity of central questions. While addressed primarily to physicists and engineers working in the field of acoustics, this expert monograph will also be of interest to mathematicians, mathematical physicists, and geophysicists.

From a brilliant Brookings Institution expert, an “important” (The Wall Street Journal) and “penetrating historical and political study” (Nature) of the critical role that oceans play in the daily struggle for global power, in the bestselling tradition of Robert Kaplan’s The Revenge of Geography. For centuries, oceans were the chessboard on which empires battled for supremacy. But in the nuclear age, air power and missile systems dominated our worries about security, and for the United States, the economy was largely driven by domestic production, with trucking and railways that crisscrossed the continent serving as the primary modes of commercial transit. All that has changed, as nine-tenths of global commerce and the bulk of energy trade is today linked to sea-based flows. A brightly painted forty-foot steel shipping container loaded in Asia with twenty tons of goods may arrive literally anywhere else in the world; how that really happens and who actually profits from it show that the struggle for power on the seas is a critical issue today. Now, in vivid, closely observed prose, Bruce Jones conducts us on a fascinating voyage through the great modern ports and naval bases—from the vast container ports of Hong Kong and Shanghai to the vital naval base of the American Seventh Fleet in Hawaii to the sophisticated security arrangements in the Port of New York. Along the way, the book illustrates how global commerce works, that we are amidst a global naval arms race, and why the oceans are so crucial to America’s standing going forward. As Jones reveals, the three great geopolitical struggles of our time—for military power, for economic dominance, and over our changing climate—are playing out atop, within, and below the world’s oceans. The essential question, he shows, is this: who will rule the waves and set the terms of the world to come?

The first book to weave Eurasia together through the perspective of the oceans and seas "A detailed account of the growing importance of the Chinese, Indian, and Russian navies and how this competition is playing out in waters stretching from the Indo-Pacific area to the Arctic and the Mediterranean."--Lawrence D. Freedman, Foreign Affairs Eurasia's emerging powers--India, China, and Russia--have increasingly embraced their maritime geographies as they have expanded and strengthened their economies, military capabilities, and global influence. Maritime Eurasia, a region that facilitates international commerce and contains some of the world's most strategic maritime chokepoints, has already caused a shift in the global political economy and challenged the dominance of the Atlantic world and the United States. Climate change is set to further affect global politics. With meticulous and comprehensive field research, Geoffrey Gresh considers how the melting of the Arctic ice cap will create new shipping lanes and exacerbate a contest for the control of Arctic natural resources. He explores as well the strategic maritime shifts under way from Europe to the Indian Ocean and Pacific Asia. The race for great power status and the earth's changing landscape, Gresh shows, are rapidly transforming Eurasia and thus creating a new world order.

Waves are everywhere in our daily life. We all experience sound and light with our ears and eyes, we use microwaves to cook, and radio waves are transmitted from and are received by our cell phones. These are just some examples of waves that carry energy from point A to B. However, we may not know details of the physics underlying all these waves. It is important to understand the mechanisms that generate wave dynamics for a given system. It is not straightforward to explain how an electromagnetic field becomes oscillatory and propagates as a wave. Waves sometimes represent the underlying dynamics of observed phenomena at a fundamental level of physics. This book is designed to explore these mechanisms by discussing various aspects of wave dynamics from as many perspectives as possible. The target audiences are undergraduate students majoring in engineering science and graduate students majoring in general engineering. Going beyond the typical approach to learning science, this book discusses wave dynamics and related concepts at various levels of mathematics and physics, sometimes touching on profound physics behind them. This book was written to help readers learn wave dynamics on a deep physical level, and develop innovative ideas in their own fields.

ISBN: 9780521369527

This book is concerned with the ionosphere and the magnetosphere, and the theory of their effect on radio waves. It includes accounts of some mathematical topics now widely used in this study, particularly W. K. B. approximations, Airy integral functions and integration by steepest descents. The subject is divided into ray theory and full wave theory. Ray theory is useful for high frequencies when the ionosphere is treated as a horizonally stratified medium. The discussion of the magnetosphere, whose structure is more complicated, includes an account of whistlers and ion cyclotron whistlers. The book has been planned both for final year undergraduates and as a reference book for research. It is suitable as a course book on radio propagation for students of physics or electrical engineering or mathematics. Some of the topics are presented from an elementary viewpoint so as to help undergraduates new to the subject. The later parts are more advanced. Because the subject is so large and has seen many important recent advances, some topics have had to be treated briefly, but there is a full bibliography with about 600 references.

Wireless Power Transfer (WPT) is considered to be an innovative game changing technology. The same radio wave and electromagnetic field theory and technology for wireless communication and remote sensing is applied for WPT. In conventional wireless communication systems, information is "carried" on a radio wave and is then transmitted over a distance. In WPT however, the energy of the radio wave itself is transmitted over a distance. Wireless communication technology has proven to be extremely useful, however in future it should be even more useful to apply both wireless communication and wireless power technologies together. There are various WPT technologies, e.g. inductive near field WPT, resonance coupling WPT, WPT via radio waves, and laser power transfer. Recent Wireless Power Transfer Technologies via Radio Waves focusses on recent technologies and applications of the WPT via radio waves in far field. The book also covers the history, and future, of WPT via radio waves, as well as safety, EMC and coexistence of radio waves for WPT. Technical topics discussed in the book include: Radio Wave GenerationRadio Wave Amplification with Solid States Circuit and Microwave TubesAntenna and Beam Forming TechnologiesRadio Wave Conversion/Rectification to ElectricityBattery-less Sensor Applications toward Internet of Things (IoT)Solar Power Satellite ApplicationSafety, EMC, Coexistence of Radio Waves for the WPT WPT is an old technology based on the basic theory of radio waves, however WPT is also a state-of-the-art technology for the latest applications in IoT, sensor networks, wireless chargers for mobile phones, and solar power satellite. The theory behind these technologies, as well as applications, are explained in this book.

The goals of wind wave research are relatively well defined: to be able to predict the wind wave field and its effect on the environment. That environment could be natural (beaches, the atmosphere etc.) or imposed by human endeavour (ports, harbours, coastal settlements etc.). Although the goals are similar, the specific requirements of these various fields differ considerably.This book attempts to summarise the current state of this knowledge and to place this understanding into a common frame work. It attempts to take a balanced approach between the pragmatic engineering view of requiring a short term result and the scientific quest for detailed understanding. Thus, it attempts to provide a rigorous description of the physical processes involved as well as practical predictive tools.
