Time reversal in attenuating acoustic media

In this paper we consider the problem of reconstructing sources in attenuating acoustic media using a time-reversal technique. We first justify the use of the adjoint of the attenuated wave operator instead of the ideal one for modifying the time-reversal process as a first order correction of the attenuation effect. Then we present a modified approach for higher order corrections. We use a thermo-viscous law model for the attenuation losses.
