Abstract

Overview

This document presents a standard outlining the methodology for using the Finite Difference Time Domain (FDTD) technique in the assessment of the peak spatial-average specific absorption rate (SAR) induced by wireless communication devices in the human body.

Methodology

• Validation of Numerical Models: The standard provides guidance on validating the numerical model of the device under test (DUT).
• Uncertainty Assessment: Methods to evaluate the uncertainty in SAR simulations are defined.
• SAR Determination: Procedures are detailed for determining the peak spatial average SAR within a cubical volume.
• Software Validation: Criteria for ensuring the correct implementation of FDTD simulation software are outlined.

Note on SAR Limits

It is important to note that the document itself does not establish specific SAR limits. These limits can be found in other guidelines, namely those published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) or in IEEE C95.1, underscoring the necessity of adhering to established safety guidelines to mitigate health risks associated with exposure to electromagnetic fields.
