Abstract

Overview

This study investigates excessive exposure to radiation and its adverse impact on human health by quantifying the reduction in Specific Absorption Rate (SAR) using novel metamaterials.

Findings

• A novel ELC resonator-based metamaterial is constructed to minimize SAR in mobile phones.
• The reduction is analyzed for GSM 900 MHz and 1800 MHz bands during different smartphone usages: voice calling, messaging, and video calling.
• Key findings indicate a significant decrease in SAR, suggesting protective effects against radiation on the human head and body.

Conclusion

The study concludes the importance of employing metamaterials to reduce harmful radiation absorption in human tissues during mobile phone use, highlighting critical safety measures for varying distances between the phone and the head.

Highlights from WHO and previous studies: Even low levels of tissue temperature rises could pose risks by non-thermal mechanisms, underscoring the urgency for effective radiation shielding in mobile technologies.
