dc.description.abstract This article, describes the development of a fully automated rotary polariser quasi-optical system for use at millimetric frequencies. It is reported how the system can accurately measure the rotation and ellipticity that may be induced on a linearly polarised Gaussian Beam when it passes through a magnetic material under study with ~1% error. The system is demonstrated by the automatic characterisation of a plastoferrite sample in approximately 6 hrs using the ‘Faraday Angle Resonance’ method. This was a significant time saving over the conventional reflectance method which would take a skilled researcher ~ 1 week to perform. It is also reported how measurement of the ‘Minor Faraday Angle’ can produce more accurate results at mm-wavelengths. en
