Abstract

Using a computer simulation, impedance spectra of mixtures of conducting and insulating hard spheres which have random or regular arrangements of the components are studied. These simulations can be used to calculate the a.c. electrical properties of a multi-component composite using a personal computer. It is shown in this study that a.c. impedance spectra are sensitive functions of the filling fraction and the geometrical arrangement of the components, and especially, the impedance spectra of the composite show the abnormal arc originated from the isolated clusters in the composite.
