The materials are specifically selected using a method that takes into account dielectric spectra of the fluid to which the surface is exposed and the surface itself. It has been unexpectedly found that if the dielectric spectra of the surface and the fluid are matched in a range of relative agreement, there should be no adhesion of the foulant substance on the surface. In some embodiments, the dielectric spectra to be matched include intrinsic indexes of refraction.SELECTED DRAWING: Figure 1
