Abstract

Waveguide single-frequency method has been used to measure the complex permittivity of human red blood cells in the high-frequency domain (γ-dispersion). The relationship between the dielectric and physiological characteristics of human blood is described. It was experimentally detected that changes in complex permittivity of blood caused by the action of endogenous epinephrine in vitro can serve as criterion for assessing the functional state of the human body in health and disease. It opens an opportunity of using this method in the biomedical field for diagnostic purposes.
