(a) The dependence of CD on tilt angle θ. The result of the far field model is fitted to the experimental data by introducing a coupling efficiency factor ηc as a fitting parameter. (b) Far field CD map ηc = 47%, which produces the best fit. The tilt axis θ in (b) ranges from 0° to 90° with 10° steps.
