Özet

In this study, the frequency dependence of the focalization point was investigated for a sonic crystal lens with a triangular lattice configuration. Theoretical and experimental study results showed that focalization point location of the sonic crystal lens with a triangular lattice configuration depended on the frequency of the wave source in the second frequency band. This property of the sonic crystal lens enables shifting of the focalization point location by means of the frequency of a single acoustic source, and it can find application in technologies based on acoustic wave focusing.
