Two methods for oblique propagation in two dielectric examples of helicoidal bianisotropic mediums - chiral sculptured thin films and chiral smectic liquid crystals - are compared: (i) the series solution method, and (ii) the piecewise homogeneity approximation method. Both have to be numerically implemented, although only the former relies on an exact analytic solution of the frequency-domain Maxwell postulates. Convergence in the series solution method is investigated via calculations for a variety of planewave-illumination parameters and constitutive properties. Likewise, the maximum slice thickness for convergent results from the piecewise homogeneity approximation method is also studied. The computational efficiencies of both methods are compared.
