  • Title: Dielectric properties of human placenta, umbilical cord and amniotic fluid.
    Author: Peyman A, Gabriel C, Benedickter HR, Fröhlich J.
    Journal: Phys Med Biol; 2011 Apr 07; 56(7):N93-8. PubMed ID: 21364261.
    Abstract:
    The dielectric properties of freshly delivered human placenta, umbilical cord and amniotic fluid have been acquired at 37 °C and in the frequency range of 200 MHz-10 GHz. The experimental data were fitted to a Cole-Cole expression. The results show that dielectric properties of the umbilical cord are significantly higher than placenta due to the presence of high water content Wharton's jelly. The results also demonstrate large differences in the dielectric properties of amniotic and cerebrospinal fluids. The data presented can be used in numerical simulations of the exposure of pregnant women to electromagnetic fields.
