Terahertz spectrum is an emerging and promising spectrum as it provides sub-mm spatial resolution and many materials have unique fingerprints at this frequency range. However, the THz spectra suffer from high atmospheric absorption and free space path loss, limiting the propagation range. State-of-the-art THz testbed demonstrations with a bandwidth of >100 GHz are focused on a line of sight (LoS) sensing and limited to a propagation range of sub-2 m. This paper demonstrates non-LoS sensing up to the fifth order of reflection for the frequency band of 220-330 GHz with a range of >6 m.
