Electric field distribution and energy absorption in anisotropic and dispersive red blood cells.

摘要: We have studied the influence of anisotropic and dispersive nature red blood cell structure on energy absorption electric field distribution within exposed to electromagnetic fields frequencies in range from 50 kHz 10 GHz. For this purpose we generated a realistic model multilayered erythrocyte set parametric equations terms Jacobi elliptic functions. The effect dipole relaxations conductivities is taken into account dispersion for conductivity permittivity each layer (cytoplasmic extra-cellular bound waters, membrane, cytoplasm external medium). Using finite element numerical technique, found that absorbed membrane show well-defined maxima both normal parallel orientations with respect symmetry axis cell. tangential permittivities are shown be responsible different peak amplitudes frequency shifts maxima. A previously unnoticed shape combined water layers leads very high amplification factor (greater than 300) at megahertz range.
