Learned infinite elements
Thorsten Hohage, Christoph Lehrenfeld, Janosch Preuss
We study the numerical solution of scalar time-harmonic wave equations on unbounded domains which can be split into a bounded interior domain of primary interest and an exterior do…
A spectrally accurate method for the dielectric obstacle scattering problem and applications to the inverse problem
Thorsten Hohage, Frédérique Le Louër
We analyze the inverse problem to reconstruct the shape of a three dimensional homogeneous dielectric obstacle from the knowledge of noisy far field data. The forward problem is so…
On the well-posedness of the damped time-harmonic Galbrun equation and the equations of stellar oscillations
Martin Halla, Thorsten Hohage
We study the time-harmonic Galbrun equation describing the propagation of sound in the presence of a steady background flow. With additional rotational and gravitational terms thes…
Maximal Spaces for Approximation Rates in -regularization
Philip Miller, Thorsten Hohage
We study Tikhonov regularization for possibly nonlinear inverse problems with weighted -penalization. The forward operator, mapping from a sequence space to an arbitrary Ba…
Weighted Data Spaces for Correlation-Based Array Imaging in Experimental Aeroacoustics
Hans-Georg Raumer, Carsten Spehr, Thorsten Hohage +1
This article discusses aeroacoustic imaging methods based on correlation measurements in the frequency domain. Standard methods in this field assume that the estimated correlation…
Sweeping preconditioners for stratified media in the presence of reflections
Janosch Preuß, Thorsten Hohage, Christoph Lehrenfeld
In this paper we consider sweeping preconditioners for time harmonic wave propagation in stratified media, especially in the presence of reflections. In the most famous class of sw…
