Time Reversed Absorbing Conditions
Résumé
The aim of this paper is to introduce the time reversed absorbing conditions (TRAC) in time reversal methods. These new boundary conditions enable one to ``recreate the past'' without knowing the source which has emitted the signals that are back-propagated. This new method does not rely on any {\em a priori} knowledge of the physical properties of the inclusion. We prove an energy estimate for the resulting non-standard boundary value problem. Two applications to inverse problems are given.
