Electromagnetic absorption of the human body at the ICNIRP reference level shows the double-humped frequency characteristics : the first peak appears at several tens megahertz where whole-body resonance occurs and the second at 2GHz caused by the increased reference level. Absorption mechanism at these frequency bands is not well understood. Main purpose of this paper is to clarify the difference of absorption mechanism between resonance frequency and GHz bands in comparison of a whole-body average SAR for anatomically based model with those for a homogeneous anthoropomorphic model and cuboids. We employed a finite difference time domain (FDTD) algorithm incorporated with UPML(Uniaxial Perfectly Matched Layer) absorption boundary condition. As a result, we found that the electromagnetic absorption peak at resonance frequency bands greatly depends on the electric properties of tissue, while the peak absorption at GHz band is affected by the model surface area. It is also found that the calculated peak SAR for a 5-year-child model exceeds the safety limit specified in the guideline by 23%, and the cuboid model allows us to roughly predict the peak value of whole body average SAR.
