The periodic structure of 1-3 piezocomposite phononic crystal minimize the influence of coupling of the parasitic modes on the deliberately excited plane modes and prevent the propagation of unwanted Lamb waves. In this article, the band structures of centered square phononic crystals of PZT-5H rods in polyethylene terephthalate matrix have been studied using the numerical method of finite elements. In particular the phoninic band gaps of the system have been investigated as functions of the volume of the PZT element at the center of the unit cell of the considered crystal, under the condition of constant filling fraction of PZT rods. The results indicate that the band structure of the system contain three gap whose width vary by the volume. These gaps have extended in the (normalized) frequency range 1100 m/s to 2530 m/s Particularly it is shown that when the all PZT rods of the system are of the same size, the maximum achievable band gap of the system attains.
