Book Description
Keys, wallet, cell phone . . . ready to go! Cell phones have become ubiquitous fixtures of twenty-first-century life—suctioned to our ears and stuck in our pockets. Yet, we’ve all heard whispers that these essential little devices give you brain cancer. Many of us are left wondering, as Maureen Dowd recently asked in the New York Times, “Are cells the new cigarettes?” Overpowered brings readers, in accessible and fascinating prose, through the science, indicating biological effects resulting from low, non-thermal levels of non-ionizing electromagnetic radiation (levels considered safe by regulatory agencies), coming not only from cell phones, but many other devices we use in our homes and offices every day. Dr. Blank arms us with the information we need to lobby government and industry to keep ourselves and our families safe.

Book Description
When Thomas Edison began wiring New York City with a direct current electricity distribution system in the 1880s, he gave humankind the magic of electric light, heat, and power; in the process, though, he inadvertently opened a Pandoras Box of unimaginable illness and death. Dirty Electricity tells the story of Dr. Samuel Milham, the scientist who first alerted the world about the frightening link between occupational exposure to electromagnetic fields and human disease. Milham takes readers through his early years and education, following the twisting path that led to his discovery that most of the twentieth century diseases of civilization, including cancer, cardiovascular disease, diabetes, and suicide, are caused by electromagnetic field exposure. In the second edition, he explains how electrical exposure does its damage, and how electricity is causing our current epidemics of asthma, diabetes and obesity. Dr. Milham warns that because of the recent proliferation of radio frequency radiation from cell phones and towers, terrestrial antennas, Wi-Fi and Wi-max systems, broadband internet over power lines, and personal electronic equipment, we may be facing a looming epidemic of morbidity and mortality. In Dirty Electricity, he reveals the steps we must take, personally and as a society, to coexist with this marvelous but dangerous technology.

Book Description
This practical text gives engineers and technicians at all levels an easy-to-follow entry point into the subject of RF/EM wave propagation and antennas. While aimed primarily at those who are entering the field or transitioning from a related field, the book also helps experienced professionals obtain a more refined understanding of the various methodologies and processes in this area. The book covers the essentials, practices, technical details, and considerations needed to help a team of engineers design, install, and/or predict the technical performance of a new (or even existing) one-way, two-antenna (long radiating distance) RF communication system. The chapters are organized logically to walk you step by step through the application processes, showing you proven methods to bring about top performance, while also helping you factor in unanticipated variances, including those caused by the earth itself, earth’s gaseous atmosphere, rain, snow, hail, ice, ionospheric signal attenuation, and EM waves. This kind of understanding and consideration saves time, money, and much frustration in a project. With this book in hand, you will better understand RF/EM wave propagation and the technical vernacular used to describe it; become familiar with the various processes and considerations in analyzing, designing, and predicting the performance of new and existing antenna RF communications systems; and more confidently approach problem solving and possible solutions for reducing signal interference and loss. The chapter contents, while not sparing the reader exposure to radiated RF system design and analysis terminology, are written in a relaxed, conversational tone and easy-to-understand manner, making this a perfect learning tool for those entering or transitioning to this field, as well as an excellent supplement or foundational text for an instructional course. The book’s logically organized and easy-to-access chapter structure also facilitates its use as a bench reference for quick lookup or review.

Book Description
An introduction to RF propagation that spans all wireless applications This book provides readers with a solid understanding of the concepts involved in the propagation of electromagnetic waves and of the commonly used modeling techniques. While many books cover RF propagation, most are geared to cellular telephone systems and, therefore, are limited in scope. This title is comprehensive-it treats the growing number of wireless applications that range well beyond the mobile telecommunications industry, including radar and satellite communications. The author's straightforward, clear style makes it easy for readers to gain the necessary background in electromagnetics, communication theory, and probability, so they can advance to propagation models for near-earth, indoor, and earth-space propagation. Critical topics that readers would otherwise have to search a number of resources to find are included: * RF safety chapter provides a concise presentation of FCC recommendations, including application examples, and prepares readers to work with real-world propagating systems * Antenna chapter provides an introduction to a wide variety of antennas and techniques for antenna analysis, including a detailed treatment of antenna polarization and axial ratio; the chapter contains a set of curves that permit readers to estimate polarization loss due to axial ratio mismatch between transmitting and receiving antennas without performing detailed calculations * Atmospheric effects chapter provides curves of typical atmospheric loss, so that expected loss can be determined easily * Rain attenuation chapter features a summary of how to apply the ITU and Crane rain models * Satellite communication chapter provides the details of earth-space propagation analysis including rain attenuation, atmospheric absorption, path length determination and noise temperature determination Examples of widely used models provide all the details and information needed to allow readers to apply the models with confidence. References, provided throughout the book, enable readers to explore particular topics in greater depth. Additionally, an accompanying Wiley ftp site provides supporting MathCad files for select figures in the book. With its emphasis on fundamentals, detailed examples, and comprehensive coverage of models and applications, this is an excellent text for upper-level undergraduate or graduate students, or for the practicing engineer who needs to develop an understanding of propagation phenomena.

Book Description
Appeals to a Wide Audience Fueled by more than 30 years of intensive research and debate on the impact of electromagnetic fields (EMF) on everyday life—starting with residential exposure to magnetic fields and the development of childhood cancer in the 70s and continuing with risk of exposure via wireless communications in present day—Epidemiology of Electromagnetic Fields addresses ongoing public and scientific controversy surrounding the possible effects of electromagnetic fields (EMF) to human health, and provides an in-depth introduction into the methodology of environmental epidemiology that is appropriate for all levels, from student to practicing engineer. Exposure to EMF Focusing primarily on EMF examples, the author presents the general principles and methodological concepts in environmental epidemiology. Topics of importance in the first part of the book include epidemiological study designs, exposure assessment methods and implications for the study results, as well as selection bias, confounding, and other biases including reverse causality and ecological fallacy. The second part of the book covers environmental epidemiological methods in detail and outlines key examples such as childhood leukemia and exposure to extremely low-frequency magnetic fields, as well as examples that look at brain tumors and mobile phone use. The book also offers a detailed discussion on the range of EMF sources and exposures. In addition, it highlights the sophisticated assessment methods required to address exposure situations, and provides a historical perspective. The third part of the book examines how EMF exposure from the use of wireless communication techniques and other challenges affect risk assessment today and also details future developments. Explores environmental epidemiological methods in detail, while critically discussing epidemiological findings Provides a state-of-the-art overview of the scientific evidence of the health effects of EMF Considers how novelty, the steep increase of radiofrequency (RF) EMF exposure from wireless communications, and other challenges affect risk assessment today Epidemiology of Electromagnetic Fields provides a thorough overview of the subject, and evaluates the scientific evidence surrounding the possible health effects of EMFs.
