| Abstract [eng] |
A new air-coupled slow A0 Lamb wave mode excitation method by using matched size phased ultrasonic array has been created. The pitch of the matched size phased array is equal to the Lamb wavelength in the material under the test. By applying the new air-coupled method, the slow A0 Lamb wave mode can be excited in thin isotropic plastic films when the A0 Lamb wave mode phase velocity is lower than the sound velocity in the air. |
