Dispersion of Surface Waves in a Periodically Laminated Piezoelectric Half-Space with Liquid Upper Layer

An approach is proposed to set up the dispersion equations for surface waves propagating through a periodically laminated piezoelectric medium, with the upper layer being a perfect compressible fluid. The approach is based on the formalism of Hamiltonian periodic systems. The dispersion equations derived are valid for an arbitrary law of variation in properties with periodicity coordinate. The influence of the liquid layer and inhomogeneity of the piezoelectric medium on the dispersion spectra of surface waves is studied__________Translated from Prikladnaya Mekhanika, Vol. 41, No. 3, pp. 55–61, March 2005.
