Variation of capacitance with location of two dielectrics between both measurement electrodes using long distance capacitor

The measurement system for a permittivity distribution has been investigated based on the measured capacitance using long distance measurement electrodes with a shield and additional electrodes. However, it has not been established to measure the permittivity distribution yet. The authors have compared the experiment results with numerical ones using long distance capacitor with two acrylic rods. In the paper, we discuss the variation of capacitance with locations of two acrylic rods between both measurement electrodes.
