In this paper an approach based on the calculation of longitudinal and transverse operators is presented. The paper is devoted to the interesting topic of electromagnetic-wave propagation in complex (chiral) media. The studied process allows the analysis of guidedstructures with chiral-medium components. In this case the equations are continuously coupled. Using the longitudinal equations, we analyze wave propagation in a parallel-plate chirowaveguide consisting of two parallel perfectly conducting planes filled with a lossless, homogeneous, isotropic chiral material. The main feature of the guides is that the propagation modes are always hybrid. In addition, bifurcated modes exist with the same cutoff-frequency values and unequal propagation characteristics. We address here the issue of wave propagation in a rectangular chirowaveguide, by means of longitudinal and transverse operators. This topic was first addressed by Engheta and Pelet. (IEEE Trans. Antenna Propag. 38, 90 (1990)). We rederive their results, using a method based on a new mathematical approach that seems to be original.PACS Nos.: 41.20.Jb
