Abstract:
An ultrasound system for inspecting an object is provided. The ultrasound system includes an electromagnetic acoustic transducer (EMAT) and a pulser-receiver system. The EMAT is configured to generate acoustic signals representative of the area being inspected and comprises a flux concentrating non-conductive pole piece separating a radio frequency (RF) coil and a magnet. The pulser-receiver system is coupled to the EMAT and configured to receive the acoustic signals and convert the acoustic signal to electrical signals.
