A mode-matching method is used to accurately analyze the quasi-TE
m0
mode in ferrite slabs symmetrically loaded ridged and grooved waveguides.Numerical results are identical to those in the references.Further computation indicates that the ferrite slabs loaded ridged waveguide has broadband frequency properties and the grooved waveguide has greater differential phase shift.With higher modes considered
this method is superior to those in literatures published in recent years.
