Abstract :
We evaluated the induced SAR in an inhomogeneous model of the human body for exposure to EM waves from a dipole antenna at 400 MHz. In particular, we compared the results for the homogeneous and inhomogeneous models. For the main result, a large difference in the SAR distributions was observed. Additionally, the peak SAR averaged over 1g or 10g of tissue obtained in the homogeneous model are overestimated as compared with those in the inhomogeneous model, only when the antenna-model distance is small.
