Abstract
This research article manifests the influence of mechanically and dielectrically conducting interface on the characteristics of surface wave transmission in a piezo-structure with flexoelectric effect at the nanoscale level. The considered model consists a piezoelectric (Lithium Niobate (LiNbO3)) layer resting on piezoelectric (lead zirconate titanate (PZT-5H)) half-space. The imperfect interface includes mechanically compliment and dielectrically weakly conducting interface, mechanically compliment and dielectrically highly conducting interface, mechanically debond interface and dielectrically insulating interface. Complex dispersion relations are obtained analytically in determinant form corresponding to electrically open and short circuit cases. A numerical example has been provided to highlight the influences of different affecting parameters (like layer thickness, flexoelectric parameter, degree of dielectric and mechanically imperfect interface) on the phase velocity curve. Salient outcomes of the present study have been shown graphically.
