Abstract
We consider an electrically conducting medium with conductivity inhomogeneities in the form of sheets of thickness 2epsilon. In this setup we provide a rigorous derivation of the leading terms in the asymptotic expansion of the steady state boundary voltage potentials, as epsilon --> 0. In the two-dimensional case our derivation confirms the results, heuristically obtained in [E. Beretta et al., Z. Angew. Math. Phys. 52 (2001) 543-572].File | Dimensione | Formato | |
