2610 Efficient Generation of a Guided Wave using a Magneto-strictive Sensor and Reflector with Actual Sensor Setting

Efficient generation and detection of a guided wave in a pipe was proposed with a fixed band as a wave-reflector. In the novel efficient setting, detected amplitudes were varied as functions of a location of the reflector and the frequency of the guided waves. The method with the reflector took 2.8 times larger amplitude than that without reflector. Defect detections were also carried out to evaluate the method in comparison with the normal method.
