Abstract
A resonator method for measuring the dielectric properties of strongly absorbing materials, which enables one to detect small variations in the permittivity, is developed. By this method, the permittivity of fresh (without anticoagulants) venous and capillary blood and its variation in the process of clotting with time is determined. The dependence of the reflection coefficient of the resonator at the resonance frequencies of the permittivity of venous blood in the course of reading of the glycaemic profile is studied, and a certain correlation between the variation in the glucose content in blood and these quantities is found. The dependence of the reflection coefficient of the resonator loaded to the human hand in the process of reading of the glycaemic profile is studied, and it is shown that the correlation between the glucose content in human blood and the reflection coefficient of the resonator is observed only in the initial section of the increase in the glucose content in blood after glucose intake.
