Owing to the substantial bandwidth they offer, the exploration of 100+ GHz frequencies for wireless communications has surged in recent years. These sub-Terahertz channels are susceptible to blockage, which makes reflected paths crucial for seamless connectivity. However, at such high frequencies, reflections deviate from the known mirror-like specular behavior as the signal wavelength becomes comparable to the height perturbation at the surface of the reflectors. Such reflectors are considered electromagnetically "rough" which results in random non-specular reflection components that are not well understood. In this dataset, we present experimental results on the impact of rough scattering on over-the-air data links as well as the characteristics of ultra-broadband THz reflection response.more » « less
