Numerical Validation of Optimization Approach for Solution of Coefficient Inverse Problem in Pseudo-Frequency Domain

• We present a Lagrangian approach for the solution to an acoustic coefficient inverse problem. Given data in the pseudo-frequency domain, after the Laplace transform, we minimize a time-independent Tikhonov functional using the Lagrangian method. We study also the dependence of the reconstruction on the regularization terms in the Tikhonov functional.
