This research is focused on the theoretical modeling and experimental measurements for the dispersion relations of guided waves propagating in different temperature gradient of plates. A theoretical model based on a recursive asymptotic stiffness matrix method (RASM) with recursion computation algorism is used to provide numerical calculations for the dispersion relations. A laser ultrasound technique is used to measure the 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. This study is useful to thermometry in different temperature gradient environment in a non-contact and non-destructive ways.
