Nonlinear Acoustical Imaging

This book first introduced the theoretical foundation of nonlinear acoustics such as the basic equations of nonlinear acoustics followed by a statistical mechanics approach to nonlinear acoustics, then a curvilinear spacetime approach to nonlinear acoustics, then a gauge invariance approach to nonlinear acoustics, and application of chaos theory to nonlinear acoustics.  Various formats of nonlinear acoustical imaging are given such as B/A nonlinear parameter acoustical imaging, fractal imaging, harmonics imaging, nonclassical nonlinear acoustical imaging, and modulation method in nonlinear acoustical imaging with their applications.

Dr. Woon Siong Gan completed his BSc in physics in 1965, his DIC in acoustics & vibration science in May 1967 and his PhD in acoustics in February 1969, all from the Physics Department of the Imperial College London. He served as an associate professor in the Physics Department of Nanyang University, Singapore from 1970 to 1979. From 1979 to 1989 he was a practicing acoustical consultant. In 1989, he founded Acoustical Technologies Singapore Pte Ltd, a research & technologies company focusing on ultrasound technologies, especially acoustical imaging. The company has since developed and patented the scanning acoustic microscope (SAM) and the surface acoustic wave (SAW) devices. He is also the author of the book: Acoustical Imaging: Techniques and Applications for Engineers, published by John Wiley & Sons in June 2012.  He is the first to introduce transport theory into condensed matter physics in 1966.  Transport theory is today the foundation of theoretical design of materials.  He is the first to introduce symmetry property into acoustic fields in 2007.
