Abstract:
This report describes research on Faraday rotation and associated phenomena in magnetic materials. The Faraday rotation associated with a ferrite loaded cylindrical waveguide exhibits sharp discontinuities and oscillations when the ferrite diameter becomes an appreciable fraction of the waveguide diameter. Extensive experimental measurements of Faraday rotation versus applied magnetic field for ferrites of different lengths and diameters are presented. Two types of theoretical analyses are presented. One uses a direct solution to the boundary value problem involved to determine the mode spectra and its contribution to Faraday rotation. The other uses transmission line equivalent circuits. When two propagating modes are present in the ferrite loaded section, sharp breaks and oscillations are predicted in the Faraday rotation similar to that observed experimentally. Results of these theoretical calculations are presented.
