This model showcases the time reversal of acoustic waves.

|
|
|
The principle of time reversal
|
|
|
(https://en.wikipedia.org/wiki/Time_reversal_signal_processing) is to use the
|
|
|
reversibility of the wave equation in non dissipative media to back-propagate a
|
|
|
signal on the source that first emitted it. Time Reversal Mirrors (TRM),
|
|
|
designed by Matthias Fink and his team in the 1990's, are composed of a large
|
|
|
number of transducers which can play alternatively the role of emitters and
|
|
|
receivers. Associated to a numerical treatment module, they are able to record a
|
|
|
signal, time reverse it, and back propagate it into the medium. The applications
|
|
|
are numerous, such as submarine communication or kidney stone destruction.
