The degeneracy of TE and TM modes in a transversely magnetized ferrite slab is investigated from the dispersion diagram. The Bragg reflection phenomena in the periodic structures are employed to measure the propagation characteristics of both modes in the vicinity of the degenerate point. A theoretical study of the Bragg reflection phenomena in a surface-corrugated polycrystalline YIG slab is carried out on the basis of an equivalent-circuit model, and then experiments are performed. Existence of the degeneracy of TE and TM modes in the millimeter wave frequencies is confirmed experimentally.
