In this work, we numerically examine the usage of a sonic strip waveguide having a phononic crystal. This structure could have important applications in acoustic circuits. The well known finite difference time domain (FDTD) method was used for the simulations. Several different matrix materials were considered for the waveguide structure. All three polarizations of the input pulse where examined and the effects of all the geometric parameters of the waveguide structure have been considered in this study.
