On the time-domain full waveform inversion for time-dissipative and dispersive poroelastic media

This paper concerns the Time-Domain Full Waveform Inversion (FWI) for dispersive and dissipative poroelastic materials. The forward problem is an initial boundary value (IBVP) of equations with a memory term; FWI formulated as minimization least-square misfit function constraint. In this paper, we derive adjoint problem, whose solution can be applied to computed direction steepest descent in iterative process minimization. has similar numerical structure hence solved by same solver. Because tracking energy evolution plays important role equations, analysis system also carried out paper.
