Abstract

A detailed dosimetry in the inner ear is performed using the FDTD algorithm with a subgridding method. A head model is exposed to a mobile phone radiation and the electromagnetic field in the region of the inner ear is computed with increased numerical resolution by factor of 3, 5 and 7. Results show that increase of the numerical resolution without increase of the geometrical resolution does not give more detailed SAR distribution in the inner ear. Therefore a new model of the cochlea with increasing the geometrical resolution from 1 mm to 1/7 mm and dosimetry in this model is presented.
