Abstract
It is proposed an extension of the D-bar method of Electrical Impedance Tomography (EIT) for obtaining, as well as the conductivity, the permittivty between a 2D domain. The algorithm is based on the constructive uniqueness proof by Brown e Uhlmann (Comm. in PDEs, 22, 1997) for once-differentiable conductivities and extended to include unique determination and reconstruction of the permit…
