  The interaction between fully-submerged elastic plates and surface waves is
of high interest to optimize wave energy converters such as the "Wave Carpet".
This study focuses on the interaction between an elastic plate and waves from
an experimental point of view. To do so, a submerged thin elastic plate is held
at a fixed position in a wave field. The wave field is analyzed using a top
view video recording that gives access to the water height field while the
deformation of the elastic plate is recorded with a side view camera.
Preliminary results presented in this paper show that the elastic plate
transmits most of incoming wave energy while reflecting almost no energy. It is
also shown that dissipation arises for wavelengths less than two times the
length of the plate. Causes of dissipation are investigated emphasizing that
viscous dissipation could be responsible for the loss of energy.
