Available in PDF, EPUB and Kindle. Book excerpt: Understanding the interactions between high frequency electromagnetic waves with biological tissues, especially those in humans, are crucial in all aspects of today’s modern life where everyone is exposed to high frequency electromagnetic field, to some degree. More importantly, it can contribute to the design of electromagnetic medical imaging and therapeutic devices such as in the field of breast cancer detection and Transcranial Magnetic Stimulation (TMS). This dissertation is an attempt to provide a non-invasive and practical method for early detection of abnormalities occurred under human tissues particularly under breast tissue with the application to breast cancer detection and a novel coil design for Transcranial Magnetic Stimulation by exploring the relationship between high frequency electromagnetic field and the thermal reaction of biological tissue under the exposure of it. The presented work includes a detailed description of the relationship between the dielectric properties of biological tissue and the established electromagnetic (EM) field as well as the induced heat due to external EM field. Based on these relationships, a new design of coil has been proposed to solve one of the dilemmas encountered in TMS. Furthermore, a novel breast cancer detection technique was proposed based on traditional Thermal Imaging technique. Multi-physics simulations are used to demonstrate the validity of the operating characteristics of those techniques. A physical design of the coil and a prototype test bed for the detection technique was utilized to experimentally verify the feasibility of the method and the accuracy of the simulation results. The robustness of the detection technique was tested by using different simulation frequencies, different sizes of tumor tissue as well as different locations of the tumor. The results of this investigation indicates that the proposed methods and apparatus are feasible tools for use in the field.

Available in PDF, EPUB and Kindle. Book excerpt: A broad region of the electromagnetic spectrum long assumed to have no influence on living systems under natural conditions has been critically re-examinjld over the past decade. This spectral region extends from the superhigh radio frequencies, through de creasing frequencies, to and including essentially static electric and magnetic fields. The author of this monograph, A. S. Presman, has reviewed not only the extensive Russian literatur!;"l, but also al most equally comprehensively the non-Russian literature, dealing with biological influences of these fields. Treated also is literature shedding some light on possible theoretical foundations for these phenomena. A substantial, rapidly increaSing number of studies in many laboratories and countries has now clearly established bio logical influences which are independent of the theoretically pre dictable, simple thermal effects. Indeed many of the effects are produced by field strengths very close to those within the natural environment. The author has, even more importantly, set forth a novel, imaginative general hypothesis in which it is postulated that such electromagnetic fields normally serve as conveyors of information from the environment to the organism, within the organism, and among organisms. He postulates that in the course of evolution or ganisms have come to employ these fields in conjunction with the well-known sensory, nervous, and endocrine systems in effecting coordination and integration.

This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the early 1940's, electromagnetic energy in the nonionizing spectrum has contributed to the enhanced quality of life in a variety of ways. Aside from their well-known roles in communication, entertainment, industry and science, electromagnetic energy has come into wide spread use in biology and medicine. In addition to the intended purposes, these energies produce other effects which have been shown to influence the life processes of living organisms. It is noteworthy that these energies are not only harmless in ordinary quantities but are actually necessary for modern life, indeed without which life as we know it would be impossible. The purpose of this book is to present a succinct summary of the interaction of electromagnetic fields and waves with biological systems as they are now known. The subject matter is interdisciplinary and is based primarily on presentations scheduled for a joint symposium at the XXII General Assembly of the International Union of Radio Science, held in Tel Aviv, Israel from Tuesday, August 25 to Wednesday, September 2, 1987. The symposium was jointly sponsored by the Bioelectromagnetics Society in cooperation with the International Radiation Protection Association. The choice of topics was made to facilitate the application and to stimulate the use of nonioni zing electromagnetic energy in biology and medicine, and to increase the awareness and to promote the consideration of radiation safety by electrical engineers and experimental physicists.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to present in a concise manner what is actually known at the present time about biological effects of time invariant, low frequency and radio frequency (including microwave) electric and magnetic fields. In reviewing the vast amount of experimental data which have been obtained in recent years, the authors tried to select those results that are, in their opinion, of major importance and of lasting value. In discussing mechanisms of interaction of electromagnetic fields with living matter they have tried to differentiate between what is clearly established, what is suggested by available evidence without being convincingly proven, and what is conjecture at the present time.

This book was released on 1995-12-21 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this book has been recognized as the standard reference on biological effects of electric and magnetic fields from DC to microwaves. But much has changed in this science since the book's original publication in 1986. With contributions from eighteen leading researchers, this latest edition includes authoritative discussions of many new developments and will quickly become the new, must-have resource handbook. Dielectric properties of biological tissue are thoroughly examined, followed by chapters on physical mechanisms and biological effects of static and extremely low frequency magnetic fields. New chapters on topics that were treated very briefly in the first edition now receive extensive treatment. These topics include electric and magnetic fields for bone and soft tissue repair, electroporation, and epidemiology of ELF health effects. The chapter on computer methods for predicting field intensity has been substantially revised to describe new numerical techniques developed within the last few years and includes calculations of power absorbed in the human head from cellular telephones. The chapter discussing experimental results on RF interaction with living matter now contains information on effects of very high power, very short duration pulses. A new appendix on safety standards is based on the latest publications of governmental, as well as quasi-governmental organizations (such as the U.S. Council on Radiation Protection) in the United States, Europe, and Australia. With all its revisions, this updated version of the CRC Handbook of Biological Effects of Electromagnetic Fields provides the most comprehensive overview available of this rapidly changing science.

This book was released on 2013-03-09 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: The editors are pleased to present these Proceedings of the V Course of the "International School of Radiation Damage and Pro tection" of the "E. Majorana Centre", held in Erice (Italy) in No vember 1983. The lectures and discussions among leading scientists in various disciplines of physics, engineering, biophysics, cellular biology, physiology and medicine from 11 countries are included in this compilation. In this volume we have attempted to explore all aspects of the interaction of static and Extremely Low Frequency (ELF: 0-300 Hz) electric and magnetic fields with biological tissue, systems and whole organisms; we considered dosimetry and what is known or pre sumed concerning basic interactions, responses from the cellular and molecular level to the whole organism. Discussions of medical appli cations as well as epidemiologic investigations related to high volt age transmission were held with critiques of methodologies used and recommendations for future approaches. Consideration was also given to the necessity and principles of setting protection standards for man and the environment. We believe this is the first attempt to put all this informa tion together into one volume to provide perspective for understand ing the influence of static and ELF electric and magnetic fields on biological systems. We hope our attempts were successful. Martino Grandolfo Sol M.
