Description
This study, conducted within the EU GOLIAT project framework, presents the numerical dosimetric assessment of near-field exposure emitted by personal devices across eight frequencies (from 700 MHz to 5800 MHz). The investigation employed four anatomically detailed virtual human models representing diverse age groups and anatomical characteristics. Using FDTD methodology, we analyzed PIFA/IFA antennas mounted on a commercial mock-up phone in multiple configurations, considering both vertical and horizontal polarizations and different locations of the mock-up phone near the phantom (device near the ear, in front of the eyes, and at the belly level), for a total of 176 use cases of wireless device for each anatomical model. Whole body average SAR was evaluated for all the tested configurations for an input power inducing a SAR10g of 1W/kg in the corresponding flat phantom. Preliminary results show a significant frequency-dependent absorption patterns, with sub-1 GHz frequencies exhibiting markedly higher exposure levels compared to higher frequency bands. The study provides crucial insights into human exposure patterns in realistic communication scenarios
