Toward Next-Generation Exposure Metrics for THz Communication Systems

The rapid evolution of 6G networks and the increasing adoption of Terahertz (THz) communication systems require the accurate and reliable exposure metrics to ensure the safe and efficient deployment, such systems operating in 0.1-10 THz frequency range. The next generation exposure metrics essential to investigate the impact of THz radiation on human being and the environment. This paper explores the induced electric field, absorbed power density and temperature rise dossimetric instead of SAR metrics at THz frequencies for human skin tissue. The results shows that the absorbed power density and temperature raise in human skin are found within standards limits given by international agencies like International commission on Non- Ionizing Radiation Protection (ICNIRP) and institute of Electrical and Electronics Engineers (IEEE). Further more we examine the current state of research on biological materials and to understand the potential biological effects of THz radiation on humans.
