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 Omega on the propagation constant and cutoff 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.
