Abstract

We consider the dissipative plate equation in a waveguide, in the case where the usual Geometric Control Condition of Bardos, Lebeau and Rauch [5] is not necessarily satisfied. More precisely, assuming that the damping is concentrated close to infinity. We prove polynomial energy decay with respect to a stronger norm of the initial data.
