Abstract:
This article, reports ‘Frequency Dependent Faraday Angle Resonance’ in a magnetic sample at millimetric frequencies for the first time using a fully automated rotary polariser quasi-optical system. This serves to compliment the original work performed by Raum at Terahertz frequencies in the Frequency independent region of a magnetic material. In addition, it is shown how the same instrument can be used further classify the performance of a Freespace Faraday Rotators, by the introduction of a new ‘ellipticity’ parameter measurement. This serves to identify what physical mechanism is responsible for the isolation that occurs across the device’s operating region, hence, providing a further insight into the operation of the device.
