Lamb Wave Frequency Diverse Array

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2022
The imaging method based on the conventional phased array (PA) can only realize angle focusing. To break through the above limitations, frequency diverse array (FDA) is first introduced from radar to Lamb wave, which opens up a possibility to realize angle-range focusing in damage localization. The energy pattern of FDA without considering the features

Time-reversed Lamb waves

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1998
Lamb waves are extensively involved in plate structure inspection because of their guided nature. However, their dispersive nature often limits their use in flaw detection. In this paper we show that the use of a time-reversal mirror (TRM) allows to automatically compensate for the dispersive nature of Lamb waves.
