Reception and Transmission of Transient Electromagnetic Fields
Author: Hans J. Schmitt
Publisher:
ISBN:
Category : Antennas (Electronics)
Languages : en
Pages : 44
Book Description
The receiving and transmitting properties of small linear antennas, conical antennas, and loops for transient electromagnetic fields were investigated experimentally. Short electrical dipoles loaded by a capacitance represented by a cathode follower can be used successfully for the measurement of transient fields with rise times of less than 1 nanosecond, if the first antenna resonance is suppressed by a series resistor at the base of the antenna. The currents induced on nonresonant structures by transient electromagnetic fields are investigated and their application to a direct measurement of the time sequence of the electromagnetic field is discussed. Signals with a simple and known time dependence such as a unidirectional pulse can be radiated into space if the reflection of current waves at discontinuities of the antenna structure is avoided. In a manner similar to that useful for the absorption of continuous waves in media with a stratified conductivity, it is shown that reflections at discontinuities can be avoided by dipoles with tapered resistive loading.

Bioengineering and Biophysical Aspects of Electromagnetic Fields, Fourth Edition
Author: Ben Greenebaum
Publisher: CRC Press
ISBN: 1351737546
Category : Technology & Engineering
Languages : en
Pages : 537
Book Description
The two volumes of this new edition of the Handbook cover the basic biological, medical, physical, and electrical engineering principles. They also include experimental results concerning how electric and magnetic fields affect biological systems—both as potential hazards to health and potential tools for medical treatment and scientific research. They also include material on the relationship between the science and the regulatory processes concerning human exposure to the fields. Like its predecessors, this edition is intended to be useful as a reference book but also for introducing the reader to bioelectromagnetics or some of its aspects. FEATURES New topics include coverage of electromagnetic effects in the terahertz region, effects on plants, and explicitly applying feedback concepts to the analysis of biological electromagnetic effects Expanded coverage of electromagnetic brain stimulation, characterization and modeling of epithelial wounds, and recent lab experiments on at all frequencies Section on background for setting standards and precautionary principle Discussion of recent epidemiological, laboratory, and theoretical results; including: WHO IARC syntheses of epidemiological results on both high and low frequency fields, IITRI lab study of cancer in mice exposed to cell phone-like radiation, and other RF studies All chapters updated by internationally acknowledged experts in the field

Measuring the Radio Frequency Environment
Author: Edward N. Skomal
Publisher: Springer
ISBN:
Category : Juvenile Nonfiction
Languages : en
Pages : 388
Book Description
The radio-frequency environment has an obvious and direct influence on the performance of electronic systems that depend upon the transfer of energy through space for their operation. Examples of such systems include radio communications, radio navigation, radar, and commercial AM, FM, and television broadcast systems. Less obvious, but nonetheless significant, is the influence the radio-frequency environment can have on electronic systems that ostensibly do not depend on the transfer of energy through space, for example, the degradation caused by electromagnetic fields generated by citizens band radios, radars, lightning, power lines, and electrostatic discharges on the performance of computers, process control equipments, automotive elec tronics and biomedical instrumentation. The beneficial and deleterious effects of man-made and naturally occurring electromagnetic fields on biological systems, including human beings, although little understood at present, may have more important long-term consequences than upon in the operation of equipment. As the radio-frequency environment evolves with the progression of the electronic age, the necessity to monitor, measure, and characterize it assumes greater importance. The purpose of this book is to provide, in a single self contained volume, the necessary background and methodology needed to execute a survey of the RF environment. We have included representative data on natural and man-made ambients in a variety of settings, wave propagation fundamentals, instrumentation descriptions, survey procedures, and data ana lysis techniques. Much experimental effort has been expended during this century to es tablish an adequate body of knowledge on the radio-frequency environment.
