TE018 Dielectric-Resonator Technique for Precise Measurements of the Complex Permittivity of Lossy Liquids at Frequencies Below 1 GHz*
2004 / IEEE / 0-7803-8493-8
This item was taken from the IEEE Conference ' TE018 Dielectric-Resonator Technique for Precise Measurements of the Complex Permittivity of Lossy Liquids at Frequencies Below 1 GHz* ' We describe a novel cylindrical TE018 mode dielectric resonator used to measure the complex permittivity of liquids. We performed measurements at frequencies of 422 MHz and 970 MHz on 1-propanol alcohol, methyl alcohol, deionized water, and conductivity-standard-solutions of water and potassium chloride. Rigorous mode-matching analysis was used to determine the complex permittivity. Type B measurement uncertainties were estimated to be less than 0.01 for the relative permittivity and less than 0.01 for the loss tangent.
