Abstract

Overview

The research delves into the necessity of developing new experimental assessment procedures for compliance with exposure guidelines and safety standards, focusing on frequencies above 6 GHz.

Findings

  • Introduction of new dosimetric quantities specifically concerning epithelial or absorbed power density.
  • Development of methods to approximate peak spatial-average absorbed power density (psSab) using existing data and algorithms originally utilized for measuring specific absorption rates (psSAR).
  • Evaluation of uncertainty in transforming psSAR to psSab found to be less than 0.55 dB (13.5%), applicable to sources as close as 0.02λ from the tissue simulating media.

Conclusion

The proposed method simplifies the compliance assessment with the current safety guidelines and sets the groundwork for future enhancements in higher frequency ranges.
