Determination of Composition of the Mixture of Dry Substances Using the Dielectrometric Method
要約
The Q-factors of eigen oscillations of axial-layered structure consisting of a dielectric layer of Portland-cement with sand positioned in parallel to the end-face surface of a partially shielded half-disk dielectric resonator are investigated. We ascertained that insertion of dielectric sample into the resonator field in parallel to its lateral surface results in variation of the resonator eigen frequencies and its Q-factor the more, the higher are the values of the real and the imaginary parts of the dielectric permittivity of the investigated material. The influence of dielectric composition and of its sighted distance upon the resonance frequency and the resonance Q-factor are investigated. The dependences of frequency variation and electronic tuning steepness of the self-oscillator based on the Gunn diode stabilized by axial-layered structure against the dielectric component composition and moisture are obtained.
