Abstract
Exposure of humans to 5G mobile communication systems may result in a local surface temperature elevation, i.e. may cause heating skin, ears and eyes. For the frequencies less than transition frequency of 6 GHz the specific absorption rate (SAR) is used to quantify the volume heating. However, according to recently published ICNIRP 2020 safety guidelines, the surface heating above 6 GHz is quantified by absorbed power density (Sab). Furthermore, an alternative dosimetric quantity referred to as transmitted power density (TPD), is also used for internal dosimetry above 6 GHz. This paper aims to review some recently developed internal dosimetry methods based on the use of Galerkin–Bubnov indirect boundary element method for the assessment of human exposure to electromagnetic fields generated by 5G mobile systems. Different tissue models have been used in the paper. Some illustrative computational results have been presented.
