Shielded coupled strip and slot guides with a thin omega pseudochiral medium layer

A method of moments combined with mode matching technique is applied to analyze the shielded coupled strip and slot line structures containing a thin plate of Omega pseudochiral medium. The boundary problems are simplified by introducing for omega medium the approximate continuity conditions. Such mathematical model allows to examine the field displacement effect appearing in the considered guide resulting from the coupling between the omega medium and modal fields. This effect has different influence on the wave parameters of the modes propagating in the coupled strip and slot guides. The phenomena occurring in the investigated structure can be applied to the design of the novel devices such as couplers or filters.
