Numerical results for the differential phase shift in the circular waveguide with azimuthally magnetized ferrite

Employing an iterative approach, an exact computation of the differential phase shift, provided by the circular waveguide, entirely filled with azimuthally magnetized ferrite, is performed in normalized form for the normal TE 01 mode. The results obtained correspond to the upper part (consisting of two separate areas) relevant to small and large values of the off-diagonal ferrite permeability tensor element, of the frequency band in which the structure exhibits phase shifting properties. They complement previous ones for the lower part of the same. The joint consideration of the new and earlier outcomes shows that the phase shift increases almost linearly with the tensor element (is almost proportional to the reciprocal of normalized guide radius) in the whole band, if the radius (the tensor element) is fixed.
