Abstract :
Plane wave propagation in layered piezoelectric phononic crystals is considered. The wavefields are calculated in terms of the transfer matrix method providing a sustainable solution through the exploitation of T-matrix in Jordan form. Representation based on eigenvalues of transfer matrix leads to numerical stability, it allows estimation of wave energy transmission coefficients for analysis of filtration properties. The results of parametric studies of elastic wave propagation in piezoelectric phononic crystal are presented.
