Abstract
We present an experimental study of the acoustic scattering by a semi-infinite plate embedded in water, using short pulse signals. The damping coefficient of Lamb modes and their retroreflection coefficient at the extremity of the plate are investigated. The results are presented for four different Lamb modes. We show that the modes with a stronger "transversal" character have a higher retroreflection coefficient.
