This work aims to provide a fundamental understanding on the dispersive behaviors of shear horizontal (SH) surface waves propagating in a layered piezoelectric nanostructure consisting of an elastic substrate and a piezoelectric nanofilm by considering the surface effects. Theoretical derivation based on the surface piezoelectricity model was conducted for this purpose. and analytic e... https://www.bekindtopets.com/top-sale-Kelway-HB-2-Soil-Acidity-and-Moisture-Probe-top-mega/
