Abstract

In this paper, we study the terahertz (THz) transmission channels from 100 GHz (0.1 THz) to 1000 GHz (1 THz) by including the effects of frequency-dependent atmospheric attenuation and diffuse reflection (non-specular scattering) due to surface roughness for short-range indoor wireless communications. First and foremost, the ITU-R Rec. P. 676-8 model has been used for this study to compute the effects of water-vapor content in the atmosphere by demonstrating the multipath channel transfer function (CTF) dynamics for line-of-sight (LoS) and non-line-of-sight (NLoS) scenarios in a simple realistic office environment. Then, the indoor multipath propagation and its impact considering rough surfaces has been investigated employing the classical Beckmann-Kirchhoff (B-K) model by using our self-developed ray tracing algorithm (RTA). Finally, the relative received power and contribution of the diffusely scattered power at 300 GHz has been illustrated at each scenario point with different surface roughness to predict the achievable signal-to-noise ratio.
