Effect of guided wave analysis and surface finish on ΔHeff by magneto microwave Kerr effect

The experimental results on magneto-microwave Kerr effect (MMKE) on seven samples of ferrites and garnets at 9.442 and 24.0 GHz have been theoretically analysed. Our earlier analysis considering only free wave propagation has been extended to take account of the guided wave nature of microwaves. Two different methods have been used to do so. It is finally found that the model in which a pure TE11mode is propagating in empty waveguide with a pure TEM mode in an unbound sample, explains the results best, The effect of surface polishing on MMKE has also been studied.
