Table 2 Shows the aspect ratios of the grains, at each figure, at a certain frequency, the critical threshold and the Dielectric constant peak.

From: Effect of grain shape elongation in direction and perpendicular to current stream (conductive or insulator) on the electrical characteristics of mixtures
