The steady diffusion across a constant thickness corrugated barrier is analyzed through the intrinsic coordinate system. Perturbation solutions are found when the thickness is small compared to the minimum radius of curvature. For a given perimeter length, diffusive transfer is decreased, while for given maximum geometric dimensions, diffusive transfer may be increased by corrugations.
