The signal processing of Lamb wave is complex because of its multi-mode and frequency-dispersion characteristics. A method to analyze symmetrical single-mode ultrasonic Lamb wave in the time domain is presented. Based on the analysis of frequency-dispersion characteristic of symmetrical mode Lamb wave, we deduced the half analytic expression of its time signal, and implemented simulation computation...
