“…We analyzed the influence of different reasons that impact on the measurement errors and we elaborated the conditions to minimize these errors. As a result the error was decreased in ten times in comparison with the data presented in [Jain & Voss, 1994]. Fig.1 presents the appearance of the computer-aided dielectrometer.…”

“…It is necessary to have laboratory conditions and the cavity of this device does not correspond to carry out mass measurements. The upper limit frequency for waveguide methods usage with reasonable errors is 140 GHz [Jain & Voss, 1994]. The majority of such methods are based on the impedance measurement of waveguide system where a sample under study is placed.…”

“…The dielectric rod is an open waveguide system where the complex electromagnetic wave propagation constant depends on complex permittivity of liquid. The electrodynamic waveguide structure similar to the proposed one was studied during the electromagnetic wave propagation in tunnels [Holloway et al, 2000] [Jain & Voss, 1994]. Fig.1 presents the appearance of the computer-aided dielectrometer.…”

“…Numerous techniques are applied to the complex permittivity (CP) measurement at microwave frequencies [1][2][3]. It is well known that both resonator [4][5][6][7][8][9][10] and waveguide [11][12][13][14][15][16][17][18][19] methods are used for the CP measurement of high loss liquids. The resonator methods use the complex resonant frequency to obtain the CP of a liquid.…”

The propagation of an electromagnetic wave in a dielectric rod placed in a high loss liquid was studied theoretically and experimentally. It is shown that the wave has a bulk character in the rod and a surface character in the liquid. The attenuation and phase velocity of this wave have strong dependence upon the dielectric properties of the liquid and the rod, while the phase velocity of this wave exceeds the light velocity in the rod material. It enables one to consider the studied wave to be similar to the Zenneck wave. A characteristic equation for the structure under study was derived and analyzed. The attenuation and phase velocity of this wave in the presence of distilled water and a water–ethanol solution were measured. Owing to these data, the real and imaginary parts of the complex permittivity of high loss liquids under test were determined. We have good agreement between the theoretical and experimental results. A differential dielectrometer based on the usage of the Zenneck wave was designed. Thus, the complex permittivity of high loss liquids with sufficiently high accuracy can be obtained. It is also possible to record a rather small difference between two similar liquids according to their dielectric properties.
