Abstract

NPL has launched a comprehensive study on its primary waveguide TRL calibration ¾-wave Line standards, in order to establish traceability in S-parameter measurements at terahertz frequencies. The WM 380 band (500-750 GHz) has been chosen to demonstrate the approach that is being taken. High precision dimensional measurements have been carried out on these Line standards and the waveguide sections that are used as measuring instrument test ports. Electromagnetic modeling and simulations have been performed to quantify the impact of the dimensional errors on the electromagnetic performance of these devices. In this paper, some preliminary results are reported and discussed.
