Abstract:

This report is a brief review of those aspects of electromagnetic-acoustic generation and detection of interest in nondestructive evaluation NDE. Since this is a developing technology, there are no standard transducer designs and practices. The principles of ultrasonic wave generation as related to electromagnetic-acoustic transducer EMAT design are emphasized. EMATs are of interest in NDE because they offer a completely noncontacting technique for generating and detecting ultrasonic waves. The report discusses theory, experimental studies, design, and applications of EMATs. Author
