Full and accessible coverage of the key concepts governing thereduction, containment, and measurement of unintentionalelectromagnetic radiation.<br> <br> The rapid proliferation of computers, CD players, and other digitalelectronic systems in recent years has made unintentionalelectromagnetic radiation increasingly difficult to control.Control and Measurement of Unintentional Electromagnetic Radiationprovides a thorough examination of the basic principles underlyingthe problem, enabling readers to design solutions and applicationsto combat it effectively. Using a simple mathematical approachlimited to algebra and trigonometry, this timely book meets thegrowing need for a more complete understanding of electromagneticphenomena. Essential reading for electronics system designers andusers as well as consultants and researchers, this book offers:<br> * An overview of intentional electromagnetic radiators — antennas<br> * Examination and modeling of sinusoidal circuit-current radiations<br> * Frequency domain descriptions of periodic voltages, including asimple method for decomposing many often-used periodic voltagewaveshapes into their sinusoidal components<br> * Easily obtainable descriptions of the measured radiations ofperiodic, time-varying circuit currents<br> * Techniques for controlling circuit-current radiations byadjusting different parameters, such as voltage amplitude andwaveshape, circuit-current path geometry and impedance<br> * Radiation containment principles — fully and partially containedradiating currents, slot antennas, and more<br> * Basic coverage of the radiation measurement process–from antennacalibration, measurement, geometry, and the measurement environmentto test-site construction and validation.
