Time Reversal (TR) concept has been proposed in the 1980s by Mathias Fink and colleagues, it is based on the symmetry of vibrations governing equations for positive and negative time, when damping effect is negligible. The main consequence of this property is the possibility of creating time reversed waves travelling back to the location where the primary waves were created. Several applications in bio mechanics, military purposes, room acoustics, structural vibrations and ultrasonics for SHM applications have been developed in literature. We just give here few papers for illustrating the different treated aspects [1, 2, 3, 4, 5, 6]
