Comparison of S-Parameter Measurements at Millimeter Wavelengths Between INRIM and NMC

摘要

This paper describes a bilateral comparison between two national metrology institutes, National Metrology Center from Singapore and Istituto Nazionale di Ricerca Metrologica from Italy. The measurands of the comparison are the scattering parameter magnitudes of waveguide components of type WR15 (50–75 GHz) and WR10 (75–110 GHz). This comparison is, to the best of our knowledge, the first of this kind performed so far. The measurement results are also compared with electromagnetic computations based on mechanical measurements on a subset of the traveling standards.
