Аннотация: The research is devoted to numeric modeling of phononic crystals with time-depended properties of periodic structure. There are many works describing phononic crystal with a tunable bandgap. The mechanism of restructuring can have a different physical nature. In this turn, we developed model of phonon crystal with fast-changing proПоказать полностьюperties, where frequency of changing and propagating wave have the same order. The influence of time-dependent characteristics on propagation of wave packets, waves with different initial phase is shown in this work. Parameters of the crystal cell are given by time-dependent; signal propagation has significant differences from the static case. It was shown that under certain conditions a phononic crystal acquires the properties of a phase filter. © Published under licence by IOP Publishing Ltd.
