Using a liquid-state approach based on Ornstein-Zernike equations, we study the behavior of a fluid inside a porous disordered matrix near the liquid-gas critical point. The results obtained within various standard approximation schemes such as lowest-order $\ensuremath{\gamma}$ ordering and the mean-spherical approximation suggest that the critical behavior is closely related to that of the random-field Ising model.

The anisotropic nature of the dipolar (fm) interactions turns out to play a more dominant role at high fluid densities where a pronounced sensitivity in the dielectric constant and a strong degree of local orientational ordering of the fluid particles along the local fields generated by the matrix are observed.
