  The paper proposes a simple and efficient method to study the dielectric
properties of composite materials modeled using very large random
resistor-capacitor (RC) networks. The algorithm is based on the Frank-Lobb
reduction scheme and analyses the frequency dependent AC conductivity,
permittivity and phase angle of composite materials. The simulation study is
based on 1056 samples of random network containing 2*10^6 components randomly
positioned in different proportion of capacitors. It has been found that these
properties exhibit similarities to the universal dielectric response of
dielectric materials. The results show that there is no variability between
samples at low and high frequencies and across the power law.
