Abstract
This paper investigates the diffraction mechanism at D-band and its polarization dependency in a concise way. The results are compared with the conventional knife edge diffraction (KED) model. A thin metal, laminated board, and a slab of absorber are used as blockage for characterization. Logarithmic fit functions are provided to demonstrate the impact of material properties in diffraction. In most of the cases, KED model provided a good agreement with measurements. The findings also suggest that the XPR is preserved in diffraction for both co-polarized and cross-polarized scenarios.
