概要

• 論文の詳細を見る

• This research is focused in the measurement and modeling for the dispersion relations of Lamb waves propagating in LiNbOS and LiTaO3 wafers. A theoretical model based on a stiffness matrix method with recursion computation algorism is used to provide numerical calculations for the dispersion relations. Also, a dry, noncontact laser ultrasound technique is used to measured dispersion multi-mode dispersion relations. For all the experiments, the measured dispersion curves show good agreement with the theoretical calculation, indicating the reliabilities in the measurement and modeling.
