Power limiting using ferrites

Some recent advances in ferromagnetic resonance theories are first briefly reviewed. It is then shown how these theories can be applied to the understanding of the power limiting process using ferrites. The "spin-wave" buildup mechanism under pulse operating conditions is described. The design problems of a waveguide ferrite power limiter is considered in some detail. Finally, operat-data from an actual power limiter using ferrites is presented to substantiate the behavior predicted by theory.
