Abstract

In this paper, an investigation is elaborated for the specific absorption rate (SAR) induced in the head of 12 year-old children having different ear dimensions. Two types of sources are employed: a mobile phone and a dipole. Both the average SAR over a mass of 10g and 1g in the head and the power budget are determined in each tissue using the finite difference time domain (FDTD) method. The differences between the results for different ear dimensions are given at 900MHz and 1800MHz. The mean and standard deviation about the SAR and power budget are also given for this age class.
