Periodically Loaded Ferrite Phase Shifters

This paper describes a general treatment of periodically-loaded ferrite phase-shifters by considering the loading essentially continuous if there are many obstacles per wavelength. Its advantage over an attempt made to treat the structure as a cascade of transmission line sections loaded by shunt susceptances is pointed out. In its generality the method can be used to analyse both cases of longitudinally- and azimuthally-magnetised ferrites. The theoretical results obtained are in general agreement with previously published experimental results.
