Abstract

Dielectric spectroscopy technique was used to investigate the dielectric properties of fluid samples from human patients such as dielectric constant, dielectric loss and
AC conductivity as a diagnostic method. Sample was placed between metal electrodes Al-Al and gold-gold. The prepared capacitors were placed between the
electrodes of dielectric spectroscopy measurement system and at room temperature and at low pressure with 10-2 Torr alternative electric field with 1 volt amplitude
(root mean square) between frequencies from 0,1Hz to 20MHz was applied on sample capacitors. Investigated sample was infected pleura fluids from lungs. As a first
observation relaxation processes at different frequencies were reported. Also observation of different conduction mechanisms and transition between conduction
mechanisms depending on applied frequency was another observation. The presence of infected cells and infected tissues may cause difference in dielectric properties.
This ability of dielectric spectroscopy can be used as a diagnostic technique in medical science. One of the main parameter was effect of time derivation for sample
fluids.
