Abstract
The condition under which the circular waveguide, loaded with a co-axial latching ferrite cylinder of azimuthal magnetization, surrounded by a dielectric toroid, exhibits properties of a nonreciprocal digital phase shifter for the normal TE 01 mode, is investigated. For simplification it is assumed that the relative permittivities of the two layers are equal. Sophisticated iterative techniques are developed and applied, employing definite roots of the characteristic equation of the geometry, derived earlier through complex Kummer confluent hypergeometric and real zeroth and first order Bessel and Neumann functions and specific real positive numbers ( L 3 -numbers), connected with some roots of the equation mentioned. It is found out that for certain numerical equivalents of the anisotropic cylinder to waveguide radius ratio ρ there are intervals from the admissible values of the off-diagonal Polder permeability tensor element of the ferrite α (0 < |α| < 1) for which the transmission line considered does not provide differential phase shift, whereas for others such a feature of the same is not observed. The influence of structure and material parameters on the width of the aforesaid intervals is analyzed.
