Some Remarks on "Radiation from a Rectangular Waveguide Filled with Ferrite" (Correspondence)

These remarks concern the solution of the boundary value problem for the case of longitudinally magnetized ferrites between two perfectly conducting parallel planes. The above-mentioned paper by Tyras and Held treated only a very special particular case of propagation in the anisotropic media. A more general approach to the problem and a general solution will be given in this note. Throughout this note the author has kept most of the notation as in the original paper.
