FDTD and RCWA Simulation Files with MATLAB Codes for Mie-tronics Supermodes and Symmetry Breaking in Nonlocal Metasurfaces

This repository contains FDTD and RCWA simulation files together with MATLAB codes used to study Mie-tronics supermodes and symmetry-breaking effects in nonlocal metasurfaces. These files and codes enable reproduction of key results on Q and Purcell enhancement, diffractive coupling, and mode formation in typical finite resonator arrays. These files and codes were used for our results presented in arXiv preprint arXiv:2511.03560 and arXiv preprint arXiv:2507.11995
