Abstract:
In 2000, Francini solved the inverse conductivity problem for twicedifferentiable conductivities and permittivities. This solution was considered to be the first approach using Dbar methods with complex conductivities. In 2012, based on Francini's work, Hamilton introduced a reconstruction method of the conductivity distribution with complex values. The method consists of six steps. A voltage potential is applied on the boundary. Solving a DBar equation gives the complex conductivity. In this paper, the stability of the DBar equation is studied via two approximations, t^{exp} and t^{B}, for the scattering transform. The study is based on rewriting the reconstruction method in terms of continuous operators. The conductivity is considered to be non smooth.
