Abstract :
The dispersive properties of phononic crystals can be utilized to manipulate the phononic impedance of a material and to engineer the frequency-delay response of time domain signal processing circuits. In this paper we study, in both the frequency and time domains, the dispersive properties of phononic crystals formed in thin suspended plates of aluminum nitride.
