Query: Diffusion in Modulated Media   We study the motion of Brownian particle in modulated media in the strong
damping limit by using {\em toy model}, with special emphasis on the transition
from localise to diffusive behavior. By using model potential we have seen the
localised behavior when the number of minima of the potential is finite in the
asymptotic time limit. In the limit of infinite number of minima we have seen
the diffusive behavior.We calculate exactly the diffusion coefficient in
periodic field of force. We have also studied the transport in commensurate and
incommensurate media.
