How to calculate warburg factor in nyquist plot during EIS test?

11 November 2016 0 2K Report

how to calculate Warburg factor (σω) in the following relation

Zreal=Rs+Rct+σω ω^-(1⁄2)

The slope of the plot Zreal vs. ω-1/2 in the low frequency region yields the σω where ω is the angular frequency of the applied alternating current.
