Description	We consider an elastic plate governed by the Reissner-Mindlin's model, i.e., whose equilibrium equations introduce a coupling between the vertical displacement and the rotation of the normal. This structure is made of a composite with a periodic arrangement of strongly heterogeneous materials and some characteristics of the heterogeneities are comparable to the size of the microstructures. We show that, when the size of the microstructures tends to zero, the limit homogeneous structure presents, for some wavelengths, a negative %22mass density%22 tensor. This means that there exists intervals of frequencies - the band gaps - for which wave propagation is suppressed, or restricted to certain polarizations.
