Diffraction measurements at 60 GHz and 300 GHz for modeling of future THz communication systems

Indoor wireless communication channels will be operated in the 60 GHz band soon and will work at 300 GHz and beyond in the foreseeable future. Although diffraction occurs at a multitude of objects in indoor environments and needs to be considered for reliable propagation simulations, very few work exists on this topic in the mm and sub-mm wave bands. Here, we present measurements of the diffraction at wedges (cuboids) at 300 GHz with different materials and real antennas. The measurements are used to validate theoretic descriptions of diffraction phenomena.
