2019 13th Symposium on Piezoelectrcity, Acoustic Waves and Device Applications (SPAWDA).
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
