Dependence of diffraction on thickness. By keeping a filling factor of 15.2%, the FODE at λ0 with (a) circular rod in different lattice types and (b) different rod shapes in square lattice. The magenta dash-dot line in (a) corresponds to FODE which is calculated by assuming εD = 2.9 with square lattice.
