Investigations on specific absorption rate (SAR) induced in child-like and true child head using two source models

A comparison of the specific absorption rate (SAR) induced in child-like and real child head using two source models (a tri-band mobile telephone having a patch antenna and an IEEE mobile telephone), is achieved through the use of different child head models for each age class. Both the average SAR over a mass of 10g in the head and the power budget are determined using the finite difference time domain (FDTD) method. The differences between the results for the different head models are given at 900MHz, 1800MHz and 2100MHz. A comparison is given for the power budget between the two child head models for each age class. It is found that the SAR values over 10g in a CL head are higher than that in a true child head model.
