An inverse anisotropic conductivity problem induced by twisting a homogeneous cylindrical domain
We consider the inverse problem of determining the unknown function \alpha: \mathbb{R} \to \mathbb{R} from the DN map associated with the operator div (A(x',\alpha (x_3))\nabla \cdot) acting in the infinite straight cylindrical waveguide \Omega =\omega \times \mathbb{R} , where \omega is a bounded domain of \mathbb{R}^2 . Here A=(A_{ij}(x)) , …
