Effect of heterogeneity of tissues on RF energy absorption in the brain for exposure assessment in epidemiological studies on mobile phone use and brain tumors

Abstract

We compared SAR distributions in major anatomical structures of the brain of a homogeneous and a heterogeneous model using FDTD calculations. Our results proved a good correlation between SAR values in lobes of the brain where tumors may arise more frequently. However SAR values at some specific locations were shown to be under or overestimated. Copyright © 2008 The Institute of Electronics, Information and Communication Engineers.
