Optimization approach for the simultaneous reconstruction of the dielectric permittivity and magnetic permeability functions from limited observations
Larisa Beilina, Michel Cristofol, Kati Niinimäki
We consider the inverse problem of the simultaneous reconstruction of the dielectric permittivity and magnetic permeability functions of the Maxwell's system in 3D with limited bou…

Numerical studies of the Lagrangian approach for reconstruction of the conductivity in a waveguide
Larisa Beilina, Kati Niinimäki
We consider an inverse problem of reconstructing the conductivity function in a hyperbolic equation using single space-time domain noisy observations of the solution on the backsca…

Multi-resolution parameter choice method for total variation regularized tomography
Kati Niinimäki, Matti Lassas, Keijo Hämäläinen +4
A computational method is introduced for choosing the regularization parameter for total variation (TV) regularization. The approach is based on computing reconstructions at a few…
