| Abstract | {In this article, we propose and validate theoretical and experimental methods to quantitatively assess the Debye dielectric model of membrane lipid bi-layers. This consists of two steps: permittivity measurements of biological solutions (liposomes), and estimation of the model parameters by inverse application of the Effective Medium Theory. The measurements are conducted in the frequency domain between 100 MHz and 2 GHz using a modified coaxial connector, at the temperatures of 27 and 30 °C. Estimations have been performed using a three-layered model based on the Maxwell-Wagner formulation. Debye parameters (mean value ± standard error) found from fitting experimental data are: εs- 11.69 ±0.09, ε∞ = 4.00 ±0.07 |
