The occurrence of semileaky waves in dielectric chirowaveguides is investigated. It is shown that a thin-film dielectric chiroslabguide with an achiral superstrate and in which both the film and substrate are chiral can support semileaky modes radiating energy into the substrate, provided that the chirality parameters are properly chosen.
