This paper deals with an experimental study of the conversion of an incident Lamb wave on the extremity of an immersed plate. This wave gives rise to one or several different Lamb waves propagating in the opposite direction. The converted waves are observed only after a distance from the end of the plate. Non guided waves are also observed backward in the plate. An interpretation is proposed, based on the description of Lamb waves by the Debye series.
