Abstract:
As is well known that the development of high effective and thermostable acoustic devices assumes using the acoustic waves with high coefficient of electromechanical coupling (K2) and low temperature coefficient of delay (TCD) is very important. In this paper the theoretical analysis of temperature influence on velocity of SH0 wave in YX lithium niobate plate, which contacted by one side with nanocomosite polymeric films with various concentrations of Fe nanoparticles has been carried out. Calculation showed that there exist such concentrations of Fe nanoparticles when the TCD of SH0 wave in aforementioned structure is equal 15 ppm/C. In whole the obtained results open the real prospective of use of SH0 wave in structures based on thin piezoelectric plates for development of temperature stable acoustic devices for signal processing and high sensitive sensors
