title = "Effects of surface roughness on terahertz wireless links",
abstract = "This work describes the diffuse scattering response of a terahertz data stream on metallic rough surfaces to investigate its influence on wireless channels. The measurements are performed using a wireless link with carrier frequencies operating from 100-400 GHz with transmitter and receiver modules mounted on separate rotatable rails. The acquired data are analyzed to determine the dependence of scattering pattern on surface roughness parameters, including rms height and correlation length. Fundamentals of scattering and reflections are explained and integral equation method (IEM) with an exponential correlation function is verified for theoretical predictions. The implications of surface roughness for non-line-of-sight (NLOS) paths in non-specular directions are discussed for the first time.",
