Abstract
Coming ultra-high data rate 6G networks will be deployed to sub-THz frequencies where enough contiguous spectrum can be found for these. Together with technological challenges of sub-THz RF components, the importance of understanding the propagation environment and the effect of materials on such radio link performances significantly increases. This work presents an experimental study of reflective and transmissive properties of different window glass and plastic materials using an over-the-air characterisation technique at sub-THz frequencies (110–330GHz). Here, transmissive properties are represented in terms of transmission loss. The results show that some of the studied materials demonstrate transmission losses above 30–40dB, which may require particular attention for reliable network deployments.
