A comb transducer for mode control in guided wave NDE

Investigations of the characteristics of an ultrasonic comb transducer have been performed for a range of transducer parameters. A numerical model, providing a time domain wave propagation solution for the field generated by a transducer on an elastic plate, is presented. The ability of mode selection and isolation is demonstrated, which is of practical significance in NDE.
