Mathematical modeling of axisymmetric waves in a piezoelectric fiber of circular cross section coated with thin film is studied using three-dimensional theory of piezoelectricity. Potential functions are introduced to uncouple the equations of motion, electric conduction equations. The surface area of the fiber is coated by a perfectly conducting gold material. The frequency equations are obtained for longitudinal and flexural modes of vibration and are studied numerically for PZT-4 ceramic fiber. The computed nondimensional frequencies and attenuation for fiber with and without coating are presented in the form of dispersion curves.
