| Abstract: | The reflection and transmission characteristics of guided modes in parallel-plate waveguides filled with one layer, two layer and multilayer chiral medium along the longitudinal direction are solved by multimode network theory with a rigorous mode-matching procedure. Equivalent transmission lines in the transverse cross section and multimode transmission lines in the longitudinal direction are employed, and the symmetrical property of the structure in the longitudinal direction is considered so that the whole analysis can be simplified. The numerical results for different cases are presented. The effect of chirality and geometric parameters of the chiral medium on the reflection and transmission characteristics of guided modes is discussed. |
