摘要: Abstract The AC conductivity response in a broad frequency range of disordered materials is great interest not only for technological applications, but also from theoretical point view. Jonscher's power exponent value, and its temperature dependence, very important parameter dielectric data analysis as well the physical interpretation conduction mechanisms materials. In some cases has been reported to be greater than 1 at low regime. This fact seems contradict universal dynamic response. present work focuses on spectroscopy measurements polymeric materials, below ∼100 MHz. apparent n gets values 0
