Dispersion of electromagnetic waves in a coaxial line filled with ferrite

By solving Maxwell’s equations the exact dispersion equation for electromagnetic waves propagating in a layered coaxial ferrite line is obtained. In particular the analytical consideration is carried out for a simpler case of complete filling of the coaxial line with ferrite (i.e. homogeneous ferrite line). The behavior of dispersion curves of TEM - electromagnetic waves, as well as E - and H - waveguide electromagnetic waves, is investigated.
