In this paper the propagation of non-homogeneous waves in visco thermo elastic piezoelectric plate is studied with the application of linear elasticity theory. The considered plate is resonator in nature. The stress strain equations are formulated using non homogeneous form of three dimensional linear elasticity theory. The solution of the problem is derived using the Bessel function of first and second kind. The irregular boundary conditions are evaluated using the Fourier expansion collocation method. The numerical computations are carried out for triangle, square, pentagon and hexagon shapes of resonator plates. The dispersion curves are presented for the physical variables.
