Abstract :
The adverse health effects of human exposure to RF-EMFs have become of increasing concern. The safety is evaluated on the basis of the SAR. Variability in the SAR caused by differences in the physical features of real people is one of the several important issues. In this study, we developed the computational human models with different body-types by our proposed volume deformation technique to generate the model from magnetic resonance imaging data of target persons using existing human models. We also demonstrated SAR characteristics in human models with different body-types exposed to vertically and horizontally polarized EM waves ranging from 30 MHz to 6 GHz using the multi-GPU accelerated three-dimensional FDTD solver.
