We have investigated the estimation of the location of a dielectric from the capacitance measured with widely spaced measurement electrodes provided with a shield and additional electrodes. In order to investigate the estimation method, a numerical technique was developed for calculating the capacitance between widely spaced measurement electrodes by finite element analysis. We discuss the new method for estimation of the locations of two dielectrics by using a capacitor with widely spaced parallel electrodes and additional electrodes. © 2010 Wiley Periodicals, Inc.
