Propagation characteristics of the rectangular waveguide inhomogeneously filled with uniaxial omega media

We address, in this paper, the main features of hybrid modes propagating in a rectangular waveguide partially filled with pseudochiral Omega-slabs. Fo r the particular case of a uniaxial Omega-slab, we show that LSE and LSM hy brid modes can propagate in this inhomogeneously filled rectangular wavegui de. The influence of the Omega-parameter, which characterizes the magnetoel ectric tensors of the bianisotropic slat, on LSM modes is analyzed-namely a n increase in the bandwidth for monomodal operation is reported. In additio n, a field displacement effect and a variable phase shift proportional to t he change of the Omega-parameter are attained. Finally, it is shown that th e propagation characteristics are independent of the direction of propagati on and so, unlike the case of magnetically biased ferrite loading, reciproc al devices can be achieved.
