Basic Properties of Chiral Waveguides
要約
Physical properties of mode behavior in a waveguide filled with chiral medium have been analyzed. Mathematical and physical models of mode propagation have been defined and the mode classification has been proposed. It was shown that modes of a chiral waveguide have the same root singularity in dispersion as a non-chiral waveguide. However the mode transfiguration that determines a complex behavior pattern of summary dispersive curves is typical for all modes of the chiral waveguide. The modes of chiral waveguides are characterized by polarization coupling, wave mode coupling, dispersive curve gushes, spatial beats and consecutive variations of an eigen function at the operating point moving along the dispersive curve (mode transfiguration). A polarization selection of propagated waves is realized in the chiral waveguide. Therefore when the propagation constant has high values there are only clockwise-polarized waves in the chiral waveguide; it is caused by the mode transfiguration.
