    Acoustic wave focusing in complex media using Nonlinear Time Reversal coded signal processing

  • Original language description

    Nonlinear Time Reversal in systems having localized nonlinearities has been demonstrated in several complex media: acoustic waves through materials with defects[1], and recently for electromagnetic signals in systems containing a passive harmonic generating nonlinear element[2]. Recent ten years have seen considerable development (both in numerical and experimental aspects) of optimized signal processing methods for improving Non Destructive Testing (NDT) methods derived from Nonlinear Elastic Wave Spectroscopy (NEWS). Using symmetry invariance, nonlinear Time Reversal (TR) and reciprocity properties, the classical NEWS methods are supplemented and improved by new excitations having the intrinsic property of enlarging frequency analysis bandwidth and time domain scales[3]. This is the case of TR-NEWS, recognized as a useful tool for microcracks detection of various complex samples, but also for nonlinear scatterers localization. Associate TR-NEWS experiments have been validated by the
