Abstract

Overview

With the rapid development of mobile communication technology, the complexities of mobile phone design have increased, prompting significant research into the electromagnetic radiation they emit towards the human head.

Methodology

• A daily usage model of mobile phones was created.
• Using this model, the safety of human head exposure to mobile phone radiation was evaluated.
• The generalized polynomial chaos (gPC) method was utilized to create a proxy model for the specific absorption rate (SAR) across different frequencies.
• Parameter uncertainty quantification (UQ) was performed.

Findings

The study utilized the Sobol method to measure the impact of various factors on the SAR levels.

• The gPC method proved effective in saving time and costs while ensuring accuracy.
• Significant influence of the mobile phone's electromagnetic materials on the SAR value was noted, impacting safety standards.

Conclusion

Insights from this study can inform the design of safer mobile phone electromagnetic materials, thereby enhancing user safety concerning electromagnetic radiation exposure.
