ON THE DERIVATION OF THE GENERALIZED TELEGRAPHISTS EQUATIONS FOR FULL-WAVE ANALYSIS OF CHIROWAVEGUIDES

This letter discusses a formulation of the generalized telegraphist's equations for the rigorous analysis of chirowaveguides that has recent ly been reported in the literature. It is found that when a chiral med ium is in contact with the perfect electric conducting wall of the wav eguide, the boundary conditions are not satisfied on the wall, A new f ormulation is proposed to overcome this limitation. Both formulations are applied to the calculation of the dispersion diagrams and field di stributions of the completely filled parallel-plate chirowaveguide and the results are compared, Our proposed formulation is found to provid e satisfactory results when analyzing such a structure.
