چکیده
Emphasis in the paper is placed on describing guided wave successes and challenges for applications in aircraft, composite materials and pipeline inspection. Guided wave imaging methods discussed includes such topics as line of sight, tomography, guided wave C scan, phased array, and ultrasonic vibration methods. Applications outlined encircles lap splice, bonded repair patch, fuselage corrosion, water loaded structures, delamination, and ice detection and de-icing of various structures, along with crucial aspects of pipeline inspection. Successes and challenges encountered over the past decade are outlined.
