Summary: We consider generalized chessboard structures where the local conductivity takes two values \(a\) and \(b\). All integer combinations of \(a\) and \(b\) which make the components of effective conductivity matrix integer valued are found. Moreover, we discuss the problem of estimating the effective conductivity matrix by using the finite-element method.
