It has been analyzed physical features of the modes behavior in a waveguide filled with the chiral medium. Both mathematical and physical models of their propagation have been defined and modes classification has been suggested. It has been shown that the same root feature in dispersion is typical both for chirowaveguide modes and for the unchiral waveguide; however the mode transfiguration is peculiar to all chirowaveguide modes and this determines the complex character of the final dispersion curves behavior. The following features are typical for chirowaveguide modes: connections between polarizations and between wave types, intersections of the dispersion curves, the spatial beatings and consecutive changes of the eigen function while moving the operating point along the dispersion curve (the mode transfiguration). The chirowaveguide performs polarization selection of propagating waves in such a way that only right-polarized waves can exist under big values of propagation constant in the chirowaveguide; the mode transfiguration is the reason of this.
