Hölder-Logarithmic Stability and Convergence Rates for an Inverse Random Source Problem
Philipp Mickan, Thorsten Hohage
In this paper, we investigate an inverse random source problem concerned with recovering the strength of a random, uncorrelated acoustic source from correlation measurements of emi…
Inverse obstacle scattering regularized by the tangent-point energy
Henrik Schumacher, Jannik Rönsch, Thorsten Hohage +1
We employ the so-called tangent-point energy as Tikhonov regularizer for ill-conditioned inverse scattering problems in 3D. The tangent-point energy is a self-avoiding functional o…
A new numerical method for scalar eigenvalue problems in heterogeneous, dispersive, sign-changing materials
Martin Halla, Thorsten Hohage, Florian Oberender
We consider time-harmonic scalar transmission problems between dielectric and dispersive materials with generalized Lorentz frequency laws. For certain frequency ranges such equati…
