This repository contains two RETICOLO codebases:

• V7-reticolo-blazr/ contains the v7 version of RETICOLO, with Matlab wrappers for grating design and related examples.
• V9/ contains the v9 version of RETICOLO, including support for multilayer structures.

The Examples/ folder collects ready-to-run material for exploring the codebase:

• Gratings/ contains scripts that build lamellar and blazed grating structures and export meshgrid visualizations.
• Simulations/ contains complete RCWA runners together with precomputed results and plots.
• Optical_Constants/ contains refractive-index data files used by the examples.
• Reference_Data/ contains experimental and third-party benchmark data for comparison.
• helpers/ provides shared Matlab utilities used by the example runners.
