Abstract

The authors give a brief description of the transport properties in fractal materials and present results concerning the dependence of the power law exponent on the applied electric field. Interesting properties concerning the anisotropic structure of grading materials which can revealed by analyzing this dependence are discussed. Experimental data are presented, indicating the validity of the CTRW (continuous-time random walk) approach to explaining the power law time-dependence of the decaying current in composite materials
