Abstract :
We have improved the measurement uncertainty for rectangular waveguide vector network analyzer (VNA) measurements in the WM-250 (WR 1.0), 750 GHz-1.1 THz frequency band. We developed a new waveguide flange design for precise connections and dimensional measurements to establish traceability to SI in VNA measurements. This is the first such achievement to be reported using a VNA in the terahertz frequency band.
