In a round shielded waveguide with an axial ferrite rod, there are several types of intrinsic complex waves: waves with a zero power flux, similar to complex waves of a circular two-layer waveguide with dielectric layers; complex waves with anomalous dispersion and zero flux, the physical nature of which is explained by an internal (in a ferrite) distributed power turn associated with the processes of magnetization reversal of a ferrite medium; complex waves with a nonzero power flux through the waveguide cross section.

The article discusses the features of complex waves in guiding structures associated with the asymmetry of their magnetic permeability tensor.

Complex waves with a nonzero power flux exist due to pair interaction, as a result of which energy is transferred from one wave to another. In this case, complex waves inside an interacting pair do not satisfy the orthogonality condition in the energy sense: their mutual power flux is nonzero. The lack of orthogonality is due to the asymmetry of the tensor. The orthogonality condition is satisfied only at one point in the frequency range, where the interaction of complex waves ceases, and their mutual and intrinsic power fluxes vanish.
