This paper concerns the Time-Domain Full Waveform Inversion (FWI) fordispersive and dissipative poroelastic materials. The forward problem is aninitial boundary value problem (IBVP) of the poroelastic equations with amemory term; the FWI is formulated as a minimization problem of a least-squaremisfit function with the (IBVP) as the constraint. In this paper, we derive theadjoint problem of this minimization problem, whose solution can be applied tocomputed the direction of steepest descent in the iterative process forminimization. The adjoint problem has a similar numerical structure as theforward problem and hence can be solved by the same numerical solver. Becausethe tracking of the energy evolution plays an important role in the FWI fordissipative and dispersive equations, the energy analysis of the forward systemis also carried out in this paper.
