Abstract
- The bulk acoustic wave delay lines are demonstrated both theoretically and experimentally based on the acoustic superlattices. In one bulk acoustic wave delay line, two collinear acoustic superlattices are separately located, where the generation and detection of the bulk acoustic waves are executed, respectively. A basic bulk acoustic wave delay line working at 819 MHz with the delay time of 2.46 μs was realized. Furthermore, by employing two enantiomorphous aperiodic acoustic superlattices, a broadband dispersive bulk acoustic wave delay line with the center frequency at 295 MHz has also been fabricated and investigated.
