Rigorous Analysis of Latching Phase Shifters

Ferrite latching phase shifters in a generalized waveguide geometry (grooved rectangular guide with lateral ridges) are analyzed using a combination of mode-matching and variational techniques. By this method, the double transverse inhomogeneities of the waveguide configuration and of the toroid corner magnetization are both considered exactly, leading to accurate predictions of differential phase shift and of cutoff frequencies of higher order modes.
