Replication package for "Recovery of topologically robust merging bound states in the continuum in photonic structures with broken symmetry", 2024

This replication package provides detailed instructions for replicating the results presented in the article: H. Bai, A. Shevchenko, and R. Kolkowski, "Recovery of topologically robust merging bound states in the continuum in photonic structures with broken symmetry", Nanophotonics, 14(7), 899-913 (2025), https://doi.org/10.1515/nanoph-2024-0609.

The replication instructions are provided in the PDF document "Recovery_of_merging_BICs__Replication_instructions.pdf", which contains:
- short introductory notes on the computations,
- a reprint of Fig. 2 and its caption,
- a detailed instruction on how to create a COMSOL model file for replicating the results presented in Fig. 2,
- replication instructions for Figs. 2b-e and 2h, together with Python codes to plot the results,
- brief instructions on how to replicate the other results presented in the article.

The dataset is organized into two folders:
- "Data_and_plotting_codes", which contains the original data and the Python codes to plot them (for Figs. 2b-d, 2g-i, 3b-e, 3h-i, 4b-e, 5, 6a-c, 6e, 7b-c, 7e-g, and 8), and several COMSOL model files containing the solutions and plots of electric field distributions (for Figs. 2e-f, 3f-g, 4f, 6d, 7d, and 7h)
- "Replication_of_Fig2", containing the COMSOL model files (including a model file with solution and plot for Fig. 2e) created by following the replication instructions in "Recovery_of_merging_BICs__Replication_instructions.pdf", together with the replicated data for Figs. 2b-d and 2h, and the Python codes to plot them.
