Abstract	An iterative method is employed to count the differential phase shift characteristics of normal n TE0 modes in a circular waveguide, uniformly filled with azimuthally magnetized ferrite. It takes advantage of the positive purely imaginary roots of the structure’s characteristic equation, written in terms of the complex Kummer confluent hypergeometric function, to calculate the guide radius and phase constant of the waves in normalized form at a singled out numerical equivalent of the off-diagonal ferrite permeability tensor element. The roots are figured out for a varying imaginary part of the complex first parameter of wave function. The procedure continues, until the reckoned value of the radius coincides with a selected one of the same with a prescribed accuracy. The corresponding numerical equivalent of the phase constant is accepted as the one, looked for. Computations are done for both signs of the imaginary part (of the magnetization), resulting in the phase shift. The borderlines of the area in which the latter is afforded, are specified, as well. An investigation is accomplished of the effect of the parameters of geometry on the graphically presented normalized characteristics in case of 01 TE mode.
