On homogenization of the acoustic transmission on perforated double plates
Original language description
The aim is to develop a model acoustic transmission along the interface formed by two parallel perforated plates. The transmission conditions are derived in the framework of Reissner-Mindlin?s theory under the assumption of cylindrical shapes of the holes; the homogenization based on the periodic unfolding method is applied to a fictitious transmission layer which contains the acoustic fluid and the elastic perforated plate. For a given wave frequency, we analyze asymptotics of the coupled system involving the Helmholtz equation and the Reissner-Mindlin plate equations with respect to the plate thickness and size of the holes.
