Acoustic phase conjugation is a phenomenon in which an acoustic wave is manipulated so that it effectively "reverses" its propagation direction and shape. This process can be thought of as creating a time-reversed version of the original wave. The concept has similarities to optical phase conjugation, where light waves are altered to reflect an image back to its source.
