Actually I analyzed the impedance spectroscopy of some ferrite materials with the model (RCQ)(RCQ) and found two sets of parameter. One is 'start' and 'end'. Is it means the start from lower frequency and end with higher frequncy? Again there are two R's and two C's. how to know what is for grain and what for grain boundary ? Generally Rg
its a boundary limit. You can make some rough idea of X-axis intersection at high frequency, diameter of semicircle and intersection of vertical line at low frequency values from Nyquist plot. You can put those values in start and end position. For example your charge transfer resistance near about 20 ohm, as can be guess from Nyquist plot. SO you can put the limit 10 ohm and 30 ohm in corresponding places of resistance.
