A dynamic theory on the piezoceramic polymer composite with 2-2 connectivity is presented. By adopting an approach similar to the Lamb waves in a plate, the distributions of the elastic and electric fields in a piezocomposite are solved and the dispersion curves are obtained. Based on these results, a method is developed to evaluate the sound velocity, acoustic impedance, and electromechanical coupling factor kt in a composite. The theoretical predictions are in excellent agreement with the experimental results.
