Exploiting the time-reversal invariance and reciprocal properties of the lossless wave equation enables elegantly simple solutions to complex wave-scattering problems and is embodied in the time-reversal mirror. Here we demonstrate the implementation of an electromagnetic time-reversal mirror in a wave chaotic system containing a discrete nonlinearity. We demonstrate that the time-reversed nonlinear excitations reconstruct exclusively upon the source of the nonlinearity. As an example of its…

Nonlinear time reversal of classical waves: experiment and model.

It is shown that such nonlinear objects can be purely passive (as opposed to the active nonlinearities used in previous work), and a higher data rate exclusive communication system based on nonlinear time reversal is developed.

Effect of chaos in a one-channel time-reversal acoustic mirror.

St measures of the spatial and temporal contrasts of the reconstructed signal are developed in order to gain insight on these phenomena and to distinguish between cases by studying the reversion of sound waves in two-dimensional reflecting cavities numerically.

An RCM-based model of this system as two linear chaotic cavities coupled by means of a nonlinear transfer function is developed and the harmonic field strengths are predicted to be the product of two statistical quantities and the nonlinearity characteristics.

The effects of non-uniform loss on time reversal mirrors

Time reversal mirrors work perfectly only for lossless wave propagation; dissipation destroys time-reversal invariance and limits the performance of time-reversal mirrors. Here, a new measure of

Scattering statistics in nonlinear wave chaotic systems.

Researchers systematically studied how the key components in the RCM are affected by this nonlinear port, including the radiation impedance, short ray orbit corrections, and statistical properties, and developed a quantitative understanding of the statistical scattering properties of a semi-classical wave chaotic system with a nonlinear coupling channel.

Breaking of time reversal invariance in nonlinear acoustics.

One-dimensional (1D) propagation is restricted in this study to one-dimensional propagation, for which an experimental ersatz of a time-reversal mirror can be used, and in this 1D case, the time- reversal operation applied on a plane wave can be mimicked for an antisymmetric wave form by a reflection of the plane wave onto a pressure-release interface.
