The Nyquist plots of the AM 95 % samples are noticeably different and significantly more difficult to interpret (Figure ). For all the porosities, it can be observed that the 𝒁 𝒄𝒄 is large enough to completely distort the typical TLM shape. Still, using the modified TLM model previously described tortuosity factor of the 28 % porosity samples can be reliably obtained.
