At Terahertz frequencies, commonly used indoor building materials like plaster must be considered as rough, so that rough surface scattering exerts a significant impact on ultra broadband THz propagation channels. Allowing for the modeling of scattering, the characteristics of scattered multipath components like angle and time of arrival as well as phase distributions are investigated in a small office scenario. A double directional channel model is derived in the AoA, AoD and ToA domain. The dependence of the multipath characteristics on the surface roughness is demonstrated. Exemplary channel realizations are generated according to the proposed approach and are contrasted to ray tracing simulations for the evaluation of the applicability of the model.
