In this paper, we present a new study of the electromagnetic wave propagation inside a rectangular waveguide partially loaded with an isotropic chiral medium, by means of the coupled mode method. Along this analysis some new features related to the variation of the propagation constant versus frequency and the chirality parameter, which have not been previously reported in the literature, are introduced. Among them, we highlight the existence of a frequency point wherein all the dispersion curves cross each other, and the increasing of the cutoff frequency of the fundamental mode with the chirality of the medium. © 2013 Wiley Periodicals, Inc.
