The fractional volume dependence of stopbands in piezoelectric periodical composite plates has been studied experimentally by exciting the band‐edge resonances. The frequency and symmetry of such modes below the thickness resonance of the plate are successfully interpreted in terms of a theoretical model which provides approximate dispersion curves of the lowest Lamb waves propagating in the composite plate.

Abstract

The fractional volume dependence of stopbands in piezoelectric periodical composite plates has been studied experimentally by exciting the band‐edge resonances. The frequency and symmetry of such modes below the thickness resonance of the plate are successfully interpreted in terms of a theoretical model which provides approximate dispersion curves of the lowest Lamb waves propagating in the composite plate.
