Abstract : The paper deals with the case of a ferrite slab of arbitrary dimension located near any of the walls of a rectangular wave-guide, magnetized along an arbitrary axis, for an arbitrary wave propagation mode. The solution is obtained by the perturbation method, using the solutions of the unperturbed problem in the form of LSE and LSM modes, the behavior of which was investigated under the corresponding cases by the author earlier (Izvestiya LETI, No. 47, 1962). Allowance is made for the concentration of the field in the ferrite, which plays the decisive role in the theory of operation of efficient phase shifters. Simple formulas are proposed for the ferrite-slab calculations so as to ensure maximum utilization of this effect. The calculations are confirmed by experiment. The good agreement between the calculations and the experiment for the case of a single slab leads to the conclusion that the proposed calculation procedure is valid also for other ferrite structures with analogous physical phenomena. This applies also to the phase shifter of Reggia and Spencer (Proc. of IRE, v. 45, 11, 1957).
