Abstract: In this study, we analyzed the dielectric behavior of urine among subjects with diabetes mellitus. The measurements were conducted using an open-ended coaxial probe at microwave frequencies between 0.2 and 50 GHz at room temperature (25 °C), 30 °C and human body temperature (37 °C), respectively. The strongest statistically significant difference in dielectric properties across different glycosuria groups (F (2, 41) = 8.681; p 0.5%) at low frequencies. Dielectric constant correlated positively with glycosuria level at frequency above 40 GHz while loss factor correlated negatively with glycosuria level at frequency above 15 GHz. The experimental data closely matched the Debye model.
