摘要：
In this paper, the propagation of gap wave in piezoelectric phononic crystals with slit is investigated by the plane wave expansion method (PWE). Much attention is focused on the influence of the permittivity of the filler material in the slit on the band behavior of the structure. Results show that the width of the slit significantly alters the position and the extern of the complete band gap. Our findings provide the potential of the piezoelectric phononic crystals in modulating gap wave propagation.
