   Hello there:
     
  There have been someworks on the k-dependent or spatial dependent dielectric
functions in the context of solvation dynamics of ions and dipoles in polar
solvents. Foundamentally one is interested in the response of the solvent
polarization to a infinitely small by spatially varying field. This is
different from the concepts of dielectric constants where a uniform field is
applied. 

Here is some references if anyone is interested.

D.Q. Wei and G.N. Patey, "Dynamics of molecular liquids: a comparison of
different theories with application to wave vector dependent dielectric
relaxation and ion solvation", J. Chem. Phys. 93, 1399 (1990).

P. Attard, D.Q. Wei and G.N. Patey, "Critical comments on the nonlocal 
dielectric function employed in recent theories of the hydration force",
Chem. Phys. Lett., 172, 69 (1990).

A. Chandra, D.Q. Wei and G.N. Patey, "Microscopic theory of solvation dynamic
in polar liquids", J. Chem. Phys., Oct., 1st issue, 1993.

Hope this is helpful.
