Abstract: | A numerical method is developed for studying normal electroelastic waves in a layer of piezoelectric materials with mm2 rhombic
symmetry, and a second order thickness atris of symmetry. The main system of equations is reduced to eight hamiltonian-type
equations in the thickness coordinate. For harmonic waves, the generalized spectral problem is solved numerically taking into
account the even (odd) character of the solution with respect to the central plane of the layer. Some solutions of specific
problems are analyzed.
