Abstract
A model has been developed for the detection of ultrasonic waves using electromagnetic acoustic transducers (EMATs). EMATs are particle velocity sensors, which can be designed to have sensitivity to in-plane and, or out-of- plane ultrasonic displacements, by suitably arranging the magnetic field in the receiving EMATs relative to the orientation of the coil. Good agreement between the results from modeling and experimental measurements has been demonstrated. (C) 2008 Elsevier B.V. All rights reserved.
