Magnetostrictive Sensor Technology for Long-Range Guided Wave Inspection and Monitoring of Pipe

Guided waves refer to mechanical (or elastic) waves in ultrasonic and sonic frequencies that propagate in a bounded medium (such as pipe, plate, rod, etc.) parallel to the plane of its boundary. The wave is termed guided because it travels along the medium guided by the geometric boundaries of the medium.
