Resum
Bipolar material impedance measurements are easier to implement than tetrapolar measurements but are more affected by electrode impedance. This effect can be reduced by measuring at a high-enough frequency albeit with the risk of deviations due to stray capacitances. High frequency measurements intended to reduce the influence of material conductivity when its permittivity is of interest also suffer from the effects of parasitic capacitances. In this paper, the effect of stray capacitance to gro...
