Power exponents larger than unity observed in some cases are physically acceptable within this model. A saturation high frequency region is also predicted, in agreement with experimental results. There does not exist a universal fractional power law (and is useless searching for a unique common critical exponent), but a qualitative universal behavior of the ac conductivity in disordered media.8 pages plus 3 figuresDisordered Systems and Neural NetworksSoft Condensed Mattertext
