We investigate the diffusion of a rigid rodlike object in a two-dimensional disordered host medium, which
consists of static pointlike sources of force. The points are distributed with long-range spatial correlation and
interact with the rod via a repulsive potential. The time dependence of the rodâs center-of-mass mean-squared
displacement and its rotational mean-squared displacement are obtained for various degrees of long-range spatial
correlation and rodâs lengths. These transport characteristics are compared to those obtained in previous studies for the case of homogeneous distribution of force points. It is shown that existence of long-range correlation among force points makes the center of mass diffusion anomalous.
