"dataset for paper \"A Programmable Approach to Waveguide Mode Conversion Using Random Metamaterial Modules \" Junming Zhang"

"The source files provide the structural database and corresponding electromagnetic response data used in this work. Specifically, the dataset includes the geometrical position information of randomly generated disordered structures in different waveguides, the corresponding multimode scattering matrices of each structure, and the scattering matrices of air layers with different thicknesses.The disordered structures are composed of randomly distributed scattering elements under non-overlapping constraints, with all geometrical parameters and spatial positions explicitly provided. Based on these structures, the modal scattering matrix of each configuration is extracted through numerical simulations to characterize the coupling relationships among different propagating modes. In addition, air layers are treated as independent modules, and their scattering matrices under various thicknesses are precomputed and included, enabling efficient cascading analysis of composite structures.The dataset allows reproduction of the mode-conversion results presented in this paper and supports further studies on structural combination and optimization."
