Fundamentals and Applications of Ultrasonic Waves (2^nd Ed.)

Written at an intermediate level in a way that is easy to understand, Fundamentals and Applications of Ultrasonic Waves, Second Edition provides an up-to-date exposition of ultrasonics and some of its main applications. Designed specifically for newcomers to the field, this fully updated second edition emphasizes underlying physical concepts over mathematics.

The first half covers the fundamentals of ultrasonic waves for isotropic media. Starting with bulk liquid and solid media, discussion extends to surface and plate effects, at which point the author introduces new modes such as Rayleigh and Lamb waves. This focus on only isotropic media simplifies the usually complex mathematics involved, enabling a clearer understanding of the underlying physics to avoid the complicated tensorial description characteristic of crystalline media.

The second part of the book addresses a broad spectrum of industrial and research applications, including quartz crystal resonators, surface acoustic wave devices, MEMS and microacoustics, and acoustic sensors. It also provides a broad discussion on the use of ultrasonics for non-destructive evaluation. The author concentrates on the developing area of microacoustics, including exciting new work on the use of probe microscopy techniques in nanotechnology.

Focusing on the physics of acoustic waves, as well as their propagation, technology, and applications, this book addresses viscoelasticity, as well as new concepts in acoustic microscopy. It updates coverage of ultrasonics in nature and developments in sonoluminescence, and it also compares new technologies, including use of atomic force acoustic microscopy and lasers. Highlighting both direct and indirect applications for readers working in neighboring disciplines, the author presents particularly important sections on the use of microacoustics and acoustic nanoprobes in next-generation devices and instruments.

J. David N. Cheeke received his bachelor’s and master’s degrees in engineering physics from the University of British Columbia, Vancouver, Canada, in 1959 and 1961, respectively, and his Ph.D in low temperature physics from Nottingham University, United Kingdom, in 1965. He then joined the Low Temperature Laboratory, CNRS, Grenoble, France, and also served as professor of physics at the Université de Grenoble. In 1975, Dr. Cheeke moved to the Université de Sherbrooke, Canada, where he set up an ultrasonics laboratory, specializing in physical acoustics, acoustic microscopy, and acoustic sensors. In 1991, he joined the physics department at Concordia University, Montreal, where he was head of an ultrasonics laboratory. He was chair of the department from 1992 to 2000. In 2003 he retired from Concordia University and became Vice President, Operations, of Microbridge Technologies, Inc., Montreal, a spinoff from Concordia University. He retired from Microbridge in 2006 and has lived in Victoria, BC, since that time. He has published more than 150 papers on various aspects of ultrasonics and acoustics. He is a senior member of the IEEE.
