The propagation of the surface waves in a poro-electro-elastic plate studied. The problem is solved analytically as well as numerically. The computation is done numerically for Barium Titanate 6mm poro-piezo ceramic and dispersion curves are presented. The behavior of symmetric and anti-symmetric modes of vibrations and their relation to surface acoustic waves are also studied. The effects of electro-elastic interaction, wave frequency and porosity on the phase velocities of these modes are observed.
