Book Description
Humanity's ability to produce enough food is mostly due to adoption of new methods and technologies by the agricultural industries as they became available. New information, communication and high speed processing and precision agriculture technologies have the potential to transform the agricultural industry. These technologies incorporate radio-frequency and microwave radiation into their systems. This book presents an overview of how these technologies are being used in agricultural systems. The main purpose of the book is to provide a glimpse of what is possible and encourage practitioners in the engineering and agricultural industries to explore how radio-frequency and microwave systems might further enhance the agricultural industry. The authors have extensive experience in agricultural and microwave engineering, instrumentation and communication systems.

Book Description
From engineering fundamentals to cutting-edge clinical applications This book examines the biological effects of RF/microwaves and their medical applications. Readers will discover new developments in therapeutic applications in such areas as cardiology, urology, surgery, ophthalmology, and oncology. The authors also present developing applications in such areas as cancer detection and organ imaging. Focusing on frequency ranges from 100 kHz to 10 GHz, RF/Microwave Interaction with Biological Tissues is divided into six chapters: * Fundamentals in Electromagnetics--examines penetration of RF/microwaves into biological tissues; skin effect; relaxation effects in materials and the Cole-Cole model (display); the near field of an antenna; blackbody radiation and the various associated laws; and microwave measurements. * RF/Microwave Interaction Mechanisms in Biological Materials--includes a section devoted to the fundamentals of thermodynamics and a discussion on energy and entropy. * Biological Effects--investigates the effects of radio frequency fields on the nervous system, the brain and spinal cord, the blood-brain barrier, and cells and membranes. * Thermal Therapy--includes a description of applicators and an extensive discussion on the foundation of dielectric heating and inductive heating. * EM-Wave Absorbers Protecting the Biological and Medical Environment--investigates materials for EM-wave absorbers from both a theoretical and applications perspective. Special attention is given to ferrite absorbers. * RF/Microwave Delivery Systems for Therapeutic Applications--begins with the fundamental features of major components used in RF/microwave delivery systems for therapeutic applications. New research towards the development of future measurement techniques is also presented. The book features problem sets at the end of each chapter, making it an excellent introduction for bioengineering and engineering students. Researchers, physicians, and technicians in the field will also find this an excellent reference that offers all the fundamentals, the most cutting-edge applications, and insight into future developments. An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department.

Book Description
This book examines the human auditory effects of exposure to directed beams of high-power microwave pulses, which research results have shown can cause a cascade of health events when aimed at a human subject or the subject’s head. The book details multidisciplinary investigations using physical theories and models, physiological events and phenomena, and computer analysis and simulation. Coverage includes brain anatomy and physiology, dosimetry of microwave power deposition, microwave auditory effect, interaction mechanisms, shock/pressure wave induction, Havana syndrome, and application in microwave thermoacoustic tomography (MTT). The book will be welcomed by scientists, academics, health professionals, government officials, and practicing biomedical engineers as an important contribution to the continuing study of the effects of microwave pulse absorption on humans.

Book Description
Antennas, power lines, microwave ovens, color TVs, VDTs, radar, and the RF sealers used in many industries may or may not cause harmful physical effects. In this book, Nicholas Steneck takes an objective look at the multifaceted and still unresolved debate involving government, the public, and industry over the safety and use of microwaves and radio-frequency radiation. In the process he raises important issues of conflicting values, vested interests, and scientific uncertainty. Steneck traces the origins of the debate to the 1930s, when scientific research concentrated on the therapeutic, thermal aspects of radio-frequency radiation, and he also covers such recent aspects of the story as the irradiation of the U.S. Embassy in Moscow and the continuing controversies over the siting of satellite communication antennas. Nicholas H. Steneck is Professor of History and Director of the Collegiate Institute for Values and Science at the University of Michigan.

Book Description
This general introduction to the sources and nature of RF and Microwave radiation covers the problems of RF safety management, including the use of measuring instruments and methods. Radio frequency radiation can be dangerous in a number of ways. Hazards include electromagnetic compatibility and interference, electro-explosive vapours and devices, and direct effects on the human body. The book is designed for people responsible for, or concerned with, safety. This target audience will primarily be radio engineers, but include those skilled in other disciplines including medicine, chemistry or mechanical engineering. The book covers the problems of RF safety management, including the use of measuring instruments and methods, and a review of current safety standards. The implications for RF design engineers are also examined.

Book Description
This book provides a fundamental and practical introduction to radio frequency and microwave engineering and physical aspects of wireless communication In this book, the author addresses a wide range of radio-frequency and microwave topics with emphasis on physical aspects including EM and voltage waves, transmission lines, passive circuits, antennas, radio wave propagation. Up-to-date RF design tools like RF circuit simulation, EM simulation and computerized smith charts, are used in various examples to demonstrate how these methods can be applied effectively in RF engineering practice. Design rules and working examples illustrate the theoretical parts. The examples are close to real world problems, so the reader can directly transfer the methods within the context of their own work. At the end of each chapter a list of problems is given in order to deepen the reader’s understanding of the chapter material and practice the new competences. Solutions are available on the author’s website. Key Features: Presents a wide range of RF topics with emphasis on physical aspects e.g. EM and voltage waves, transmission lines, passive circuits, antennas Uses various examples of modern RF tools that show how the methods can be applied productively in RF engineering practice Incorporates various design examples using circuit and electromagnetic (EM) simulation software Discusses the propagation of waves: their representation, their effects, and their utilization in passive circuits and antenna structures Provides a list of problems at the end of each chapter Includes an accompanying website containing solutions to the problems (http:\\www.fh-dortmund.de\gustrau_rf_textbook) This will be an invaluable textbook for bachelor and masters students on electrical engineering courses (microwave engineering, basic circuit theory and electromagnetic fields, wireless communications). Early-stage RF practitioners, engineers (e.g. application engineer) working in this area will also find this book of interest.
