THz Detector Calibration Based on Microwave Power Standards

Abstract

This paper describes the calibration process of a THz pyroelectric detector, to be traceable to a standard thermocouple sensor in WR10 waveguide-range (75-110GHz). Setup consists of a suitable waveguide-to-free-space adaptor (antenna) with relevant positioners to analyze and characterize the standing-wave ratio. The results are presented together with a preliminary error analysis and uncertainties.
