Abstract :
Following the theory of linear piezoelectricity, we analyzed propagation of guided waves in layered piezoelectric structure. The pattern is a piezoelectric plate sandwiched between two piezoelectric half spaces. The waves propagate near intermediate plate. From this, we get precise dispersion relation which can be changed into to piezoelectric surface acoustic waves. The result will help us to know better about and improve acoustic wave devices.
