Fig. 5. Real permittivity as a function of water content for bentonite. Results are from the network analyzer and the capacitance sensor. The comments between parentheses stand for uncorrected data (0), data corrected for the total dielectric losses (G), data corrected for the ionic conductivity as derived from the resistance measured in the sample (Rs), and data corrected for the ionic conductivity as derived from the resistance measured in the bucket (Rb). Plot (b) is a close-up of plot (a).
