A line-of-sight channel model for the 100–450 gigahertz frequency band

EURASIP Journal on Wireless Communications and Networking, 2021
This paper documents a simple parametric polynomial line-of-sight channel model for 100–450 GHz band. The band comprises two popular beyond fifth generation (B5G) frequency bands, namely, the D band (110–170 GHz) and the low-THz band (around 275–325 GHz).
