Abstract

Optimised discrete equivalent networks are analytically derived for zinc oxide-based ceramic and perfluoropolyether microemulsion materials. The evaluations are facilitated using the relaxation time distribution corresponding to the arc in the dielectric-constant complex plane. Arc skewing in the microemulsion material is simulated by active elements comprising negative impedance converters along with passive resistive-capacitive elements to represent negative capacitance and conductance. The network evaluation procedure is validated by comparison with experimental data
