Published RGB Filter Validation

Yang et al. Scientific Reports 5, 9285

This page statically reproduces the normal-incidence transfer-matrix setup from Figures 1 and 2 of Compact Multilayer Film Structure for Angle Insensitive Color Filtering.

The calculator handoff uses the same RGB layer thicknesses and a-Si optical constants. The plot on the right is rendered locally with the same chart template used by the tutorial pages.
