Abstract

We discuss the existence of Stark Ladder resonances in the structure of the transmission coefficient T associated with the propagation of SH piezoelectric waves in a multilayered piezoelectric medium. The structure of T is analyzed as a function of the angle of incidence θ. For periodic multilayered piezocomposite we obtain a band structure in the curves T-vs-sin2θ. However, when we add a linear term in the values of the parameters of the layers, the periodicity is lost, the bands disappear and the curves T-vs-sin2θ show a Stark-Ladder structure.
