Study on the Parameters of Cole-Cole Model

Abstract

Abstract. The paper presents ways for determining parameters of the characteristic impedance ) (s Z a , the value of time constant τ , ε ′ and ε ′ ′ , through formula transformation and frequency spectroscopy method (FDS).Finding out the values of coefficient α with Cole-Cole model. Building double-relaxation model to fit complex dielectric permittivity ε in different temperature and moisture level, and finding the influence of them on the parameters of the ColeCole model.
