Abstract
This paper shows the importance of using a cell model with the proper geometry, orientation andinternal structure to study possible cellular effects from direct radiofrequency exposure. For thispurpose, the electric field intensity is calculated, using the finite element numerical technique, insingle- and multilayer spherical, cylindrical and ellipsoidal mammalian cell models exposed tolinearly polarized electromagnetic plane waves of frequencies 900 and 2450 MHz. An extensiveanalysis is performed on the influence that the cell geometry and orientation with respect to theexternal field have in the value of the electric field induced in the membrane and cytoplasm. Wealso show the significant role that the cytoplasmic and extracellular bound water layers play indetermining the electric field intensity for the cylindrical and ellipsoidal cell models. Finally, astudy of the mutual interactions between cells shows that polarizing effects between cellssignificantly modify the values of field intensity within the cell.
