EMATs for Science and Industry: Noncontacting Ultrasonic Measurements


Overview

""EMATs for Science and Industry"" comprises the physical principles of electromagnetic acoustic transducers (EMATs) and their applications to scientific and industrial ultrasonic measurements on materials. The text is arranged in four parts. Part one is intended to be a self-contained description of the basic elements of coupling mechanisms along with practical designing of EMATs for various purposes. There are several implementations to compensate for the low transfer efficiency of the EMATs. Useful tips to make an EMAT are also presented. Part two describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of the contactless nature of EMATs and is the most successful amplification mechanism for precise velocity and attenuation measurements. Part three applies EMAR to studying the physical acoustics. New measurements emerged on three major subjects; in situ monitoring of dislocation behaviour, determination of anisotropic elastic constants and acoustic nonlinearity evolution. Part four deals with a variety of individual topics encountered in industrial applications, for which the EMATs are believed to the best solutions.
