Abstract

Overview

As 5G technologies become more prevalent, concern grows around the effects of electromagnetic fields (EMFs) on humans. This study explores how both age and the presence of clothing can influence power absorption in the upper microwave spectrum.

Findings

• Investigation focused on near-field exposure from multi-beam radiating structures at 26 GHz and 60 GHz.
• Power absorption variations due to age and textile presence were studied using four Yagi antennas and skin-equivalent models.
• Significant increases in power density were observed in aged individuals and varying effects based on textile properties like thickness and permittivity were noted.
• Presence of textile can result in increased or decreased power absorption depending on specific factors.

Conclusion

Both age and clothing materially impact the exposure levels and absorption rates of EMFs in near-field interactions typical of personal communication devices. This underscores the importance of considering these variables in developing EMF safety standards and technologies.
