Full and accessible coverage of the key concepts governing the reduction, containment, and measurement of unintentional electromagnetic radiation.
The rapid proliferation of computers, CD players, and other digital electronic systems in recent years has made unintentional electromagnetic radiation increasingly difficult to control. Control and Measurement of Unintentional Electromagnetic Radiation provides a thorough examination of the basic principles underlying the problem, enabling readers to design solutions and applications to combat it effectively. Using a simple mathematical approach limited to algebra and trigonometry, this timely book meets the growing need for a more complete understanding of electromagnetic phenomena. Essential reading for electronics system designers and users as well as consultants and researchers, this book offers:
- An overview of intentional electromagnetic radiators -- antennas
- Examination and modeling of sinusoidal circuit-current radiations
- Frequency domain descriptions of periodic voltages, including a simple method for decomposing many often-used periodic voltage waveshapes into their sinusoidal components
- Easily obtainable descriptions of the measured radiations of periodic, time-varying circuit currents
- Techniques for controlling circuit-current radiations by adjusting different parameters, such as voltage amplitude and waveshape, circuit-current path geometry and impedance
- Radiation containment principles -- fully and partially contained radiating currents, slot antennas, and more
- Basic coverage of the radiation measurement process--from antenna calibration, measurement, geometry, and the measurement environment to test-site construction and validation.
