【 摘 要 】

References(6)Cited-By(4)A trial for the excitation of a guided wave using a MHz range air-coupled ultrasonic wave in a hollow pipe is attempted. A guided wave is propagated in a 1mm thick aluminum pipe at a critical angle and transmission and reception via air are successfully accomplished. The flexural mode guided wave is detected using wavelet transformation.
