Now in a newly updated and revised edition, this timely resource provides you with complete and current details on the theory, design, and applications of wireless antennas for on-body electronic systems. the Second Edition offers readers brand new material on advances in physical phantom design and production, recent developments in simulation methods and numerical phantoms, descriptions of methods for simulation of moving bodies, and the use of the body as a transmission channel. You also find a completely revised chapter on channel characterization and antenna design at microwave frequencies. This cutting-edge volume brings you the state-of-the-art in existing applications like Bluetooth headsets together with detailed treatment of techniques, tools, and challenges in developing on-body antennas for an array of medical, emergency response, law enforcement, personal entertainment, and military applications on the horizon. the book briefs you on energy propagation around and into the body and how to estimate performance of on-body wireless links, and then dives into the nuts-and-bolts of designing antenna systems that deliver the goods. It covers on-body communication channels at microwave frequency bands and at low frequency bands, as well as ultra wideband systems for WPANs and WBANs. You get details on body-centric UWB antennas and channels, as well as advances in wearable mobile, EBG, and "smart fabric" antennas for cellular and WLAN communications. Chapters on telemedicine applications, such as remote diagnoses, and implantable medical devices cover crucial propagation issues and other obstacles that need to be addressed. Rounding out the coverage is a section on antenna design for body-sensor networks and their emerging military and space applications. Packed with hands-on guidance from noted experts, this volume will be indispensable for your efforts in designing and improving body-centric communication systems.

Antennas in Matter provides both an introduction to and a comprehensive description of the properties of antennas and probes embedded within or near material bodies such as the earth, the ocean, or a living organism. The theory and application of antennas designed to transmit and receive information between points above the earth's surface are for the most part well understood. This book presents a full treatment of a sequence of research that has become increasingly important in recent years--the use of underground antennas for communication with miners and subway trains and for the geophysical exploration of the earth's crust; underwater antennas; antennas embedded in or near living organisms for biomedical and diagnostics in tissue and layered media with electromagnetic properties as diverse as those of fat, muscle, and bone. The book has been designed to serve a dual purpose: the first and third parts, covering fundamentals and measurements, form a self-contained introduction for undergraduates and researchers in geophysics and bioengineering; the second part provides a detailed presentation of the theory for graduate students and researchers in electrical engineering and physics. The approach integrates analytical, numerical, and experimental methods for the solution of a variety of problems involving antennas and electromagnetic wave propagation in or near matter.

The Arecibo Radio Telescope (Arecibo) has made amazing findings that would otherwise have remained undiscovered. Yet, Arecibo’s inception is shrouded in mystery: unknown is the true story behind its creation, secret for all these years. Until now. In his final book, Helias Doundoulakis demystifies Arecibo for the novice, from dreams to drawings. The chronological account of the iconic telescope is made plain for all to see, which spanned six decades. Read how his brother, George Doundoulakis, undertook its conception and fielding, finally winning patent rights for his brother Helias, CIA director William Casey, and Gus Michalos. Follow the inseparable brothers on their journey of courage, inspiration, and brilliance that advanced the design of Arecibo and inspired generations of space scientists for years to come.

Light-matter interaction is pervasive throughout the disciplines of optical and atomic physics, condensed matter physics, electrical engineering, and now increasingly in biology and medicine with frequency and length scales extending over many orders of magnitude. Deep earth and sea communications use frequencies of a few tens of Hz, and X-ray imaging requires sources oscillating at hundreds of petaHz. This book provides advanced undergraduates, graduate students and researchers from diverse disciplines with the principal tools required to understand and contribute to rapidly advancing developments in light-matter interaction, centred at optical frequencies and length scales from a few hundred nanometres to a few hundredths of a nanometre. This book deploys an arsenal of powerful analytic tools to render this multidisciplinary subject in unique form, not encountered in standard Physics or Electrical Engineering text books. This new edition has been substantially expanded with almost 200 pages of new material. Several new and extended chapters treat momentum flow between fields and matter, metamaterials, and atom-optical forces applied to atomic and molecular cooling and trapping.

Based on Bahl and Bhartia's popular 1980 classic, Microstrip Antennas, this all new book provides the detail antenna engineers and designers need to design any type of microstrip antenna. After addressing essential microchip antenna theory, the authors highlight current design and engineering practices, emphasizing the most pressing issues in this area, including broadbanding, circular polarization, and active microstrip antennas in particular. Special design challenges, ranging from dual polarization, high bandwidth, and surface wave mitigation, to choosing the proper substrate, and shaping an antenna to achieve desired results are all covered.
