Ultrasonics fundamentals and applications

摘要: This book is a translation of 'Physik und Technik des Ultraschalls', originally published in 1988 by S. Hirzel Verlag, Stuttgart. As the German edition, it based on lectures ultrasound which author has given over past fifteen years to students electrical engineer ing and physics at Rheinisch-Westfiilische Technische Hochschule Aachen, Germany. Its purpose explain describe peculiarities high frequency sound with general acoustics as foundation. It these have led development specific methods generation detection one hand are relevant way propagates various materials, origin wide range technical applications other. The first part devoted fundamentals ultrasonics. Since reader not expected knowledge acoustics, introductory chapters survey basic ideas laws without systematically deriving formulae pre sented. Likewise, third chapter, deals radiation diffraction sound, still fairly general, although somewhat more adapted requirements ultrasound. In three subsequent chapters, or measurement dealt with. seventh chapter digression hypersonic range."
