Transmittance (𝒯_WAF) obtained from the simulations of frequencies ƒ₀ to ƒ₈, shown as red scatter points. The blue solid line is the analytical profile of transmittance obtained using the Leroy-1981 model. The horizontal dotted line represents the asymptotic value of the 𝒯_WAF profile having a value of 0.75 obtained using the Leroy-1981 model. The gray hatched region is where PDI was found to significantly influence the transmittance.
