Model 900, 1800, 2450 MHz (CW) exposure to stomatocyte, erythrocyte and echinocyte cells (numerical modeling) and analysis of predicted energy absorption and interaction

E-field intensities were calculated assuming 900 MHz, 1800 MHz, and 2450 MHz linear polarized exposures to single- and multi-layered spherical, cylindrical, and ellipsoidal cell models using finite element numerical techniques. The study reported that cell geometry and orientation with respect to the field can greatly influence the E-field induced in the membrane and cytoplasm. In addition, the cytoplasm and extra-cellular bound water layers play a strong role in determining the E-field intensity in cylindrical and ellipsoidal cell models. Finally, polarizing effects between cells can significantly modify the values of field intensity within cells. A second theoretical study of the internal electric field distribution in human erythrocytes exposed to 900 MHz radiation reported that in certain orientations (field aligned with minor axis), the field amplification in the membrane was higher than predicted using a spherical model. Further, the electric field in the membrane decreased as the membrane permittivity increased, and increased as the cytoplasm permittivity increased. In a subsequent study, red blood cell interaction with RF spanning the range of 50 kHz to 10 GHz was modeled.
