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 over the frequency range 105–175~GHz. We further demonstrate how these measurements can be used to estimate, with high precision, the position of the transmitter and the delays of multipath components. Our results validate the assumption made in~[1], which states that, under such propagation conditions and at these high frequencies, the contribution of non-line-of-sight (NLoS) scattered or reflected components is essentially negligible.
