User Exposure in mmW Bands: Impact of Age, Textile and Body Curvature

With the upcoming deployment of 5G and B5G, new frequencies, absent from the natural electromagnetic (EM) spectrum, have been proposed for wireless communications. In this study, we investigate the variations of the human body exposure in real conditions at 26 GHz and 60 GHz as a function of age, textile presence, and local body curvature radius. The analysis revealed that aging induces variations of the averaged absorbed power density within 10%. At 26 GHz, the variations reach 41.5% in presence of a textile for the averaged absorbed power density and 72.3% for the peak absorbed power density when the curvature radius is of 1 mm.
