Three new simple approximate methods for finding the factors of proportionality in the formulae for computation of differential phase shift, produced by the azimuthally magnetized circular ferrite waveguide, are given. The key idea in them is to figure these quantities only for one pair of working points for positive and negative magnetization of the load by an iterative technique. The pair is chosen arbitrarily, or it is connected with the envelope in the phase diagram or with the cutoff state.
