Thermal Microwave Radiation

Combines theoretical concepts with experimental results on thermal microwave radiation to increase the understanding of the complex nature of terrestrial media. Emphasising on radiative transfer models, this book covers the terrestrial aspects, from clear to cloudy atmosphere, precipitation, ocean and land surfaces, vegetation, snow and ice.

More than 80 years of experience in the practical application of electromagnetic energy in various fields of human activity (industry, agriculture, science, medicine, etc.) suggests that microwave heating is an effective application of electromagnetic energy. This book presents the latest investigations on the applications of microwave energy and the effects of microwave radiation on various materials and mediums. Divided into two sections on thermal and nonthermal effects, this volume contains eight chapters that examine the use of microwave energy to extract bioactive compounds from plant materials, for rock-breaking operations, to synthesize functional dyes and nanomaterials, and more.

Microwaves and Thermoregulation emerged from a symposium hosted by the John B. Pierce Foundation at Yale University, New Haven, Connecticut, on October 26-27, 1981. The event brought together engineers, physical scientists, physiologists, and psychologists to discuss the ways in which nonionizing electromagnetic radiation deposits thermalizing energy in biological tissues and how this energy may be detected and managed by the conscious organism. The book begins by tracing the history of thermal RF-tolerance and of thermoregulation. This is followed by chapters on topics such as the characteristics of the thermal environment; the microwave stimulus; electromagnetic heating for therapy; the effects of thermal (infrared) radiation on humans; body temperature regulation during euthermia and hyperthermia; the central nervous thermoregulatory system; and thermal sensation. Other chapters discuss the sensory dynamics of intense microwave irradiation; thermoregulation in intense microwave fields; thermoregulatory behavioral responses; and effects of long-term (subchronic) exposure to weak microwave fields. The book also includes a chapter featuring panel discussion held during the symposium, and one that discusses G. A. Sachers free-energy hypothesis of life-span enhancement.

For several years, researchers have been reporting the effects of microwave radiation/heating on both the structure and function of DNA, RNA and proteins. For the most part, favourable accelerated biological functions are observed as microwave induced heating occurs, but other not-so favourable effects are also observed, such as denaturation, fragmentation and the so called and ill-explained, non-thermal microwave effects. This volume, the first of its kind, brings researchers together from around the world to discuss their current findings and thinking on the effects of Microwaves on Biological systems, particularly DNA, RNA and proteins, in the form of contributed edited chapters.

The application of microwave energy for thermal processing of different materials and substances is a rapidly growing trend in modern science and engineering. In fact, optimal design work involving microwaves is impossible without solid knowledge of the properties of these materials. Heres a practical reference that collects essential data on the dielectric and thermal properties of microwaveable materials, saving you countless hours on projects in a wide range of areas, including microwave design and heating, applied electrodynamics, food science, and medical technology. This unique book provides hard-to-find information on complex dielectric permittivity of media at industrial, scientific, and medical frequencies (430 MHz, 915MHz, 2.45GHz, 5.8 GHz, and 24.125GHz). Written by a leading expert in the field, this authoritative book does an exceptional job at presenting critical data on various materials and explaining what their key characteristics are concerning microwaves.
