Abstract: A transmission problem for a class of dynamic coupled system of hyperbolic equations having piecewise constant coefficients in a bounded three-dimensional domain is considered. Assuming that in the entire boundary, dissipative mechanisms are present and that suitable geometric conditions on the domain and the interfaces are satisfied, we prove that the total energy associated with the model decays exponentially as $t\to+\infty$. Exact boundary controllability is then obtained through Russell's controllability via stabilizability principle.

Keywords: uniform stabilization; transmission problem; piezoelectric body.

Classification (MSC2000): 35Q99, 35Q60, 35L99.
