Le retournement temporel est un procédé physique connu de longue date dans différents domaines du spectre électromagnétique (visible, micro-onde, etc.) (et appliqué aux ultrasons par Mathias Fink à l'École supérieure de physique et de chimie industrielles de la ville de Paris) qui permet à une onde de retourner vers sa source dans le cas d'une propagation non dissipative. (fr) Time Reversal Signal Processing has three main uses: creating an optimal carrier signal for communication, reconstructing a source event, and focusing high-energy waves to a point in space. A Time Reversal Mirror (TRM) is a device that can focus waves using the time reversal method. TRMs are also known as time reversal mirror arrays since they are usually arrays of transducers. TRM are well-known and have been used for decades in the optical domain. They are also used in the ultrasonic domain.
