The field distributions of various modes in rectangular waveguides filled with uniaxial media are presented. The presented cases include aligned cases when the optic axis is parallel to one of the coordinate axes and the tilted cases when the optic axis is not parallel to any of the coordinate axes but still lies within one of the two side-wall planes. In the aligned uniaxial-z case the analytical...
A rectangular waveguide filled with a uniaxial medium is treated. Different orientations of the optic axis are considered, and the transmission characteristics of the guided waves are studied. When the optic axis is parallel to one of the $x$ -, $y$ -, and $z$ -axes, results of wave decompositions with respect to the optic axis are presented and compared with conventional transverse-to-z solutions...
Solutions of a metallic rectangular waveguide filled with uniaxial medium are obtained with a new approach. The direction of the optic axis is tilted but lying in one of the sidewall planes of the waveguide. The formulation is based on decomposition into ordinary and extraordinary waves. The proposed method seeks wavenumbers of supported travelling modes, and is also able to calculate both cutoff...
A rectangular waveguide filled with uniaxial medium is treated. Different orientations of the optic axis are considered. Results of wave decompositions with respect to the optic axis are presented and compared with conventional transverse-to-z solutions. Computations show that the effect of anisotropy not only changes the field distributions, but also leads to changes of dominant modes in the waveguide.
