Safety Assessment and Uncertainty Quantification of Electromagnetic Radiation from Mobile Phones to the Human Head

With the rapid development of mobile communication technology, design phones has become more complex, and research on electromagnetic radiation from that reaches human head important. Therefore, first all, a model phone daily use was established. Then, based established simulation model, safety exposure to evaluated. The generalized polynomial chaos (gPC) method used establish proxy specific absorption rate (SAR) at different frequencies perform parameter uncertainty quantification (UQ). Finally, Sobol quantify influence relevant variables SAR. results showed gPC can save time cost while ensuring accuracy, SAR value is greatly influenced by materials shell. Combined with above analysis, this paper provide reasonable suggestions for materials.
