Dispersion Relations For Layered Ferrite-Bearing Structures in a Rectangular Waveguide
Pieces of a rectangular waveguide with a ferrite film are used in various devices of a microwave range operated by means of an external constant magnetic field. The article deals with the electrodynamic approach in deriving dispersion equation for such a structure with consideration for the domain ferrite morphology. The problem of a rectangular waveguide with a ferrite film of domain morphology has been solved in a general form. Dispersion relations are derived as a set of linear algebraic equations for longitudinal magnetic waves in the region of a two-layered waveguide which contains a thin ferrite layer with one domain with the magnetization tensor
