The shape of an inaccessible boundary between two different media is identified by applying a dc field. The electric potential is described by Fredholm's integral equation of the first kind. Numerical processing leads to a system of nonlinear and ill-conditioned algebraic equations. Their solution causes numerical problems. A new algorithm based on the Brouwer's fixed point theorem is proposed as a solution.
