SAR Standards

Feko makes use of a local peak SAR algorithm.

The methodology in Feko for the computation of the spatial-average SAR of a cube at a given location is based on the recommendations by CENELEC1 and the IEEE23. Feko cannot follow the standards literally for MoM and FEM calculations since they have been written for SAR calculations with an FDTD code. As a result, a local peak SAR algorithm was developed for Feko which is similar and has the same goals as the algorithm proposed in P1528.14, and also takes the intentions of P1528.1, ICNIRP and the IEEE (when they set the basic restrictions) into account.
