  A conducting 1D line or 2D plane inside (or on the surface of) an insulator
is considered.Impurities displace the charges inside the insulator. This
results in a long-range fluctuating electric field acting on the conducting
line (plane). This field can be modeled by that of randomly distributed
electric dipoles. This model provides a random correlated potential with
<U(r)U(r+k)> decaying as 1/k . In the 1D case such correlations give essential
corrections to the localization length but do not destroy Anderson
localization.
