Abstract
The present paper discusses the electric field distribution when an electric field is applied between two sensing electrodes embedded in an organic coating applied on metallic substrate. The results show that current lines tend to short-circuit throughout the metallic substrate and hence the measured impedance tends to approach that of the volume located below the electrodes plus the interfacial impedance. The results obtained from the numerical model have been verified by experimental measurements on organic coatings.
