IEEE P62704-4-2019 DETERMINING THE PEAK SPATIAL-AVERAGE SPECIFIC ABSORPTION RATE (SAR) IN THE HUMAN BODY FROM WIRELESS COMMUNICATION DEVICES@ 30 MHZ TO 6 GHZ – Part 4: General requirements for using the finite-element method for SAR calculations
IEEE - The Institute of Electrical and Electronics Engineers@ Inc.
Scope
The scope of this document is to describe the concepts@ techniques@ and limitations of the finite-element method (FEM) and to specify models and procedures for validation and uncertainty assessment for the FEM when used for determining the peak spatial-average specific absorption rate (psSAR) in phantoms or anatomical models. It recommends and provides guidance on the modelling of wireless devices@ and provides benchmark data for simulating the SAR in such phantoms or models. Several methods described in this standard are based on techniques specified in IEC/IEEE 62704-1@ which is therefore included as a normative reference. This standard does not recommend specific SAR limits because these are found elsewhere (e.g. in IEEE Std C95.1 [1] or in the guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) [2]). NOTE Cubical averaging volumes are applied in all active standards for the assessment measurement of psSAR@ and are also recommended by [1]@ [2] and [3]. Other averaging volumes have been proposed@ e.g. in [2]@ and might be included in future revisions of this standard.
