Incident Power Density Assessment of Smart Surfaces for Exposure Compliance

This paper presents preliminary research on the compliance assessment of smart surfaces, which are one of the most promising technologies for 5G higher frequency band (NR2) applications. Two different approximate approaches are provided and compared with the reference approach, which is based on full-wave simulation, in terms of assessment accuracy and efficiency to verify their availability and capability quantitatively. Both the two approximate approaches can significantly reduce the assessment time while providing acceptable assessment accuracy.
