| Popis: | The specific absorption rate (SAR) produced by mobile phones in the head of children is simulated using an algorithm based in the finite difference time domain (FDTD) method. A new model based on a 10 year old child computed tomographic images was used. The electromagnetic parameters were fitted to this age. The results are compared to the SAR calculated in the head of adults. Comparison also were made with SAR calculated in the children model when using adult human electromagnetic parameters values. It is shown that in similar conditions, the SAR calculated for the children is higher than that for the adults. When using the 10 years old child model, values around 80% higher than those for adults were obtained |
