Figure 3From: Microwave open-ended coaxial dielectric probe: interpretation of the sensing volume re-visited Plots of the perceived dielectric properties as a function of frequency for four separation distances between the probe tip and Teflon cylinder: 0.0, 0.175, 0.325, and 2.0 mm, respectively. (a) Relative permittivity, and (b) conductivity.Back to article page
