Passage of electromagnetic wave through a rectangular wave guide with an active rectangular film

The proposed work examines the passage of the electromagnetic wave through a rectangular wave guide with active film and magnetized ferritic layers. Ferrimagnetic layers are located between metal planes with perfect conductivity. A dispersion equation has been obtained to calculate the constant spread in the structure in question. The dispersion equation was solved by the Jeeves-Hook method. The graphs obtained at different parameters of the film and at different values of the magnetizing field are presented.
