Abstract: In this paper, the dynamic properties of dispersed ionic conductors(DIC) are studied. Based on the random -AC-network model of three kinds of conducting bonds, a position-space renormalization method is analytically applied to the calculation of AC conductivity and dielectric response of DIC system. The effect of particle size on dynamic properties of the system is discussed for the first time.

Key words: random -AC-network, critical threshould, scaling exponent, effect of particle size, dispersed ionic conductor
