Comparison of specific absorption rate (SAR) induced in child-sized and adult heads using a dual band mobile phone

This paper gives a study and comparison of specific absorption rate (SAR) induced in a child-sized head and an adult head using a dual band mobile phone. Both the average SAR over a mass of 10g in the head and the power budget are determined in the two cases using the finite difference in time domain (FDTD) method. The differences between the results for adult and child-sized heads are discussed at 900 MHz and 1800 MHz.
