Abstract
We propose a model which explains the evolution of the frequency dependent conductivity while an organized structure appears in an initially amorphous system. We assume that the cristalline organization is connected with the existence of an anisotropy. An anisotropy parameter is calculated. An "a priori" calculation of the conductivity is developped, which correctly accounts for the experimental results obtained on "low temperature" carbons.
