Arrays of transducers can re-create a sound and send it back to its source as if time had been reversed. The process can be used to destroy kidney stones, detect defects in materials and communicate with submarines In a room inside the Waves and Acoustics Laboratory in Paris is an array ...
Time-reversed acoustics The South Anyui Suture (SAS) is located within Mesozoids of northeastern Russia, between the Verkhoyansk-Kolyma and Anyui-Chukot foldbelts. According to ex... M Fink,D Cassereau,A Derode,... - 《Reports on Progress in Physics》 被引量: 1746发表: 2000年 Chaos ...
A combination of time reversed acoustics and nonlinear elastic wave spectroscopy techniques is introduced to localize surface breaking defects in a non-destructive manner. Reciprocal time reversal is applied at two neighbouring positions in order to create a vibration dipole with high amplitudes. At surf...
The effects of time-reversed room acoustics on word recognition abilities were examined using virtual auditory space techniques, which allowed for temporal manipulation of the room acoustics independent of the speech source signals. Two acoustical conditions were tested: one in which room acoustics were...
In the field of acoustics, the ability to work directly in the time domain, with piezoelectric retina, allows pulse echo mode processing in an iterative mode. In multitarget media, such an iterative process converges on the most reflective target. In the case of an extended elastic target, ...

Time reversed waves have previously been demonstrated for relatively low frequency phenomena such as acoustics, water waves and microwaves. Many attempts have been made to extend these techniques into optics. However, the much higher frequencies of optics make for very different requirements. A fully ...
