(a) Mean value and $90\%$ prediction interval for the real part of the CM factor, $\Re \left(\mathrm{CM}\right)$. (b) Ratio between the field at the top and at the side of a cell, which is centred in the hydrogel, for different conductivities. This means that the field is always greater at the side of the cell when the ratio is less than one.
