Acoustic waves in structure “piezoelectric plate–polymeric nanocomposite film”

Paper is devoted to the investigation of SH0 acoustic waves propagating in structure “piezoelectric plate–polymeric nanocomposite film”. The analysis was carried out by the example of the polymeric nanocomposite film based on high-pressure polyethylene with various contents of CdS nanoparticles and lithium tantalate and lithium niobate plate. The resonant attenuation of investigated waves for the certain ratios of plate and film thicknesses was found. The obtained results open the prospects of the development of structures for SH0 waves consisting of nanocomposite polymeric substrates and thin piezoelectric plates. Such structures may be useful for development of various thermostable chemical and biological sensors and signal processing devices.
