Abstract :
Time Reversal (TR) is a well known spatial/temporal re-focusing process based on the time invariance of the wave equation in lossless media. This communication deals with an aspect of Time Reversal as applied to vector fields that has never been discussed before, that is, the polarization of the point source physically or synthetically located into the target point during the “sensing” phase of TR process. It will be shown its huge impact on TR focusing performances.
