Building acoustic computers with tuneable phononic crystals

Written by
Dr Banerjee and colleagues have developed a deaf band-based model to use in building acoustic computers, using tuneable phononic crystals.

For more than two decades, physicists have been investigating wave propagation in phononic crystals, a metamaterial designed to control sound waves. A recent consideration involves using phononic crystals in acoustic computing. Acoustic computers execute basic Boolean algebra computations using acoustic waves. Dirac cones make this possible but achieving them is both very difficult and rare. Professor Sourav Banerjee and his […]
