Control and Measurement of Unintentional Electromagnetic Radiation

Full and accessible coverage of the key concepts governing thereduction, containment, and measurement of unintentionalelectromagnetic radiation.

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:
* An overview of intentional electromagnetic radiators -- antennas
* Examination and modeling of sinusoidal circuit-current radiations
* Frequency domain descriptions of periodic voltages, including asimple method for decomposing many often-used periodic voltagewaveshapes into their sinusoidal components
* Easily obtainable descriptions of the measured radiations ofperiodic, time-varying circuit currents
* Techniques for controlling circuit-current radiations byadjusting different parameters, such as voltage amplitude andwaveshape, circuit-current path geometry and impedance
* Radiation containment principles -- fully and partially containedradiating currents, slot antennas, and more
* Basic coverage of the radiation measurement process--from antennacalibration, measurement, geometry, and the measurement environmentto test-site construction and validation.Elektromagnetische Abstrahlungen elektronischer Systeme stellen eines der Hauptprobleme bei deren Entwurf dar - aber viele Entwicklungsingenieure wissen nur unzureichend über die Grundlagen dieses Phänomens Bescheid. Als eines der ersten Werke auf diesem Gebiet richtet sich dieses Buch direkt an den Hardwareentwickler und steht ihm bei der Vermeidung von Abstrahlungen beim Schaltungsentwurf zur Seite.
