Inverse Problems for Screens
Emilia Blåsten, Petri Ola, Lassi Päivärinta
We study the inverse scattering from a screen with using only one incoming time--harmonic plane wave but with measurements of the scattered wave done at all directions. Especially…
Unique Determination of a Planar Screen in Electromagentic Inverse Scattering
Sadia Sadique, Petri Ola, Lassi Päivärint
We show that the far--field pattern of a scattered electromagnetic field corresponding to a single incoming plane--wave uniquely determines a bounded supraconductive planar screen.…
Partial Data Inverse Problems for Maxwell Equations via Carleman Estimates
Francis J. Chung, Petri Ola, Mikko Salo +1
In this article we consider an inverse boundary value problem for the time-harmonic Maxwell equations. We show that the electromagnetic material parameters are determined by bounda…
Inverse boundary value problem for Maxwell equations with local data
Pedro Caro, Petri Ola, Mikko Salo
We prove a uniqueness theorem for an inverse boundary value problem for the Maxwell system with boundary data assumed known only in part of the bound- ary. We assume that the inacc…
The inverse conductivity problem with an imperfectly known boundary in three dimensions
Ville Kolehmainen, Matti Lassas, Petri Ola
We consider the inverse conductivity problem in a strictly convex domain whose boundary is not known. Usually the numerical reconstruction from the measured current and voltage dat…
Inverse conductivity problem with an imperfectly known boundary
Ville Kolehmainen, Matti Lassas, Petri Ola
We show how to eliminate the error caused by an incorrectly modeled boundary in electrical impedance tomography (EIT). In practical measurements, one usually lacks the exact knowle…
