We performed dielectric measurements for a model double-layer consisting of the upper layer of water and the lower layer of Teflon in order to analyze the penetration of the electric field pattern formed by the Open-Ended coaxial probe. Observed dielectric constant exhibited an exponential-like behavior against the distance between surfaces of Teflon and the electrode in water. The penetration depth defined by the equation suggested the value of 0.18mm for the electrode with the outer diameter of outer conductor, 2.2mm. This value of the penetration depth indicates dielectric behavior obtained from these measurements reflect the structure of human skin. The present study on the penetration depth of the electric field need for dielectric measurements offer an analytical method of complex materials in-depth heterogeneity.
