Abstract

Overview

This standard outlines the finite difference time domain (FDTD) technique application specifics for determining the peak spatial-average specific absorption rate (SAR) in the human body subjected to wireless communication devices.

Findings

  • Discussion on methods to validate the device under test (DUT).
  • Assessment of uncertainty in SAR simulations.
  • Procedures for calculating peak spatial average SAR in a cubic volume.
  • Validation requirements for FDTD simulation software implementation.

Conclusion

The document does not recommend specific SAR limits but refers readers to guidelines from authoritative sources like the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and IEEE C95.1.
