Abstract

The unique properties of terahertz (THz) waves were examined, particularly in contrast to lower-frequency bands, highlighting the effects of weather conditions and material surface roughness on THz signal propagation. To address modeling challenges, the study introduced a ray-tracing (RT) approach to refine the 3D environmental model and material electromagnetic properties using minimal channel measurement data. These calibrated parameters were then applied to broader scenarios, reducing reliance on extensive measurements. Key channel characteristics—such as path loss, shadow fading, Rician K- factor, delay spread, angular spread, and Doppler effects in mobile settings—were analyzed. The research explored two distinct 6G THz use cases: indoor desktop wireless links and outdoor vehicular communications, with the latter incorporating weather-related impacts. These findings offer valuable insights for designing and assessing THz communication systems
