Study of Mode Propagation in Pseudochiral Transmission Lines
In this paper, a generic planar transmission line filled, homogeneously, with a pseudochiral omega medium is considered. It is shown that only a uniaxial omega medium can support TE and TM modes separately. Thus, for such a medium, the fields and modal equations for TE, TM and TEM mode propagation are obtained. The special case of parallel plate waveguide is solved, and the effect of pseudochirality parameter Ω on the propagation constant and cut-off frequency is considered. For TEM propagation, an equivalent circuit is given which is different from the common isotropic transmission line model. Finally, a pseudochiral stripline is analyzed, and the elements of the equivalent circuit are calculated. The results show that the properties of the line vary as the pseudochirality parameter changes.
