Abstract :
In this paper, we study the effect of the position of the averaging volume on the averaged SAR values. CENELEC proposes that the SAR, averaged over a cube with a mass of 10 g is less than 2 W/kg. Though, depending on the position of the cube, large differences can be observed. For a simple benchmark problem of a dipole antenna irradiating a sphere, we obtained differences up to 20%. If an irregular volume is considered, the SAR becomes again significantly higher.
