Axial propagation modes in locally biaxial, dielectric, helicoidal bianisotropic media (HBMs) are analyzed. Each axial propagation mode is shown to consist of two circularly polarized (transverse) plane waves and a longitudinal plane wave, all three with different spatial frequencies. The time-averaged Poynting vector of each mode is analyzed in terms of the power densities and the energy-flow directions of the transverse plane-wave components. A previously prescribed constraint on the constitutive properties of dissipative dielectric HBMs is replaced by a less restrictive one.
