| Abstract: | Ultrasonic transmission spectrum of an isotropic metal plate is measured by an ultrasonic double-transmission technique as well as theoretically evaluated. Based on the best matching between the computed and the measured transmission spectra, the Young's modulus and Poisson's ratio of the plate are reconstructed. |

| Keywords: | Ultrasonic transmission spectrum Elastic constants Inversion method |
