Abstract

Overview

The burgeoning advancements in mobile phone technology necessitate a thorough examination of electromagnetic radiation impact on the human head. This study outlines the critical importance of investigating the radiation emitted by mobile phones and its direct interaction with the human head.

Model & Methodology

• A daily use model for mobile phones was established to set the groundwork for further simulation.
• The safety evaluation of human head exposure was conducted using a sophisticated simulation model that leverages the generalized polynomial chaos (gPC) technique for proxy modeling.
• The specific absorption rate (SAR), an indicator of radiation absorption by the human head, was meticulously calculated at various frequencies to assess parameter uncertainty.

Key Findings

The simulation employed the gPC method which strikingly saved time and costs while upholding accuracy. A notable finding is the considerable influence of the mobile phone shell's electromagnetic materials on the SAR value.

Conclusion

This vital research provides invaluable insights and recommendations for designing safer electromagnetic materials for mobile phones, thereby enhancing overall public health safety concerning electromagnetic radiation exposure.
