Experimental Verification of the Sub-THz Channel Model with Application to IRS-aided Communications

By using an experimental setup we measure the wireless propagation channel in an indoor densely-furnished environment in the frequency range [105-175] GHz. We also show how starting from such measurements we can estimate with high precision the position of the transmitter and the delay of multipath components. Our results validate the assumption made in [1] which states that in such propagation conditions, and at such high frequencies, the contribution of non line-of-sight (NLoS) scattered or reflected components is essentially negligible.
