Abstract
An experimental study of the conductive properties of some liquid biological dispersed media in the EHF range
Incoming article date: 19.12.2019The work investigated the behavior of volumetric electrical conductivity (and its components) of various biological liquid media in order to determine the possibility of influencing the processes of life. In the frequency range 0-50 GHz, the following biological liquid media were studied: cold-pressed sunflower oil; sunflower oil obtained using heat treatment; fresh egg yolk and protein; Bacillus amyloliquifaciens bacteria; bacteria Escherichia coli MG1655 pXen-lux. The presence of fluctuations in the dielectric permittivity parameters, the unevenness of the frequency characteristics, in the range of 35-37 GHz, the “bursts” of values characteristic of the resonance nature of this dependence were observed on the frequency characteristics of the loss angle tangents.
