摘要：
To derive reliable channel models for future terahertz (THz) indoor communication systems, accurate propagation mechanisms of electromagnetic waves are essential. In this paper, we focus on the diffuse scattering in the THz bands, which has often been overlooked in previous work. We present a parameterized model for the diffuse scattering of different materials at 180GHz by measuring the diffuse scattering power spectrum in indoor propagation environment. New contributions representing diffuse scattering are added to the traditional specular rays in ray tracing simulation. The impact of this enrichment on the simulated indoor propagation channel is analyzed by comparing simulations taking into account or not the diffuse scattering. The simulation results demonstrate that the small-scale parameters of the channel are significantly modified when taking into account the diffuse scattering phenomenon. This means that considering the diffuse scattering component is particularly important for establishing a more realistic THz channel model.
