Evaluation of Path-Loss Models for THz Propagation in Indoor Environments

In this paper, we evaluate the path-loss models that can be adopted for indoor communications in the TeraHertz (THz) frequency band. Three different models are investigated versus distance; namely, the ITU, the log-distance (LD), and the multi-wall COST 231 models. The latter exhibits much higher path-loss than the other two because it is able to account more accurately for the interior obstacles of indoor environments.
