MetaSPR-SimDB-70K: A Physics-Aware Full-Wave Simulation Database for MetaSPR Nanophotonic Sensors

MetaSPR-SimDB-70KMetaSPR-SimDB-70K is a fabrication-aware full-wave electromagnetic simulation dataset for nanophotonic sensor field prediction. The dataset was generated from periodic MetaSPR nanophotonic structures simulated using FDTD methods under TM-like illumination.Dataset OverviewTotal samples: 70,000Structures: 175Wavelengths: 400Wavelength range: ~400–800 nmSimulation type: Full-wave FDTDMain file: unified_v6p3_260209.h5FAE json file: Combined_vectors.jsonInput Tensor (x)Channels:ε_realε_imagk0x spatial phasek0z spatial phasegeometry-aware normalized distance fieldShape:[5, H, W]Output Tensor (y)Channels:Ex_realEx_imagEz_realEz_imagHy_real × Z0Hy_imag × Z0Shape:[6, H, W]Z0 = 376.73 ΩGlobal Condition Vector (cond)cond[0] = normalized free-space wavenumbercond[1] = k0 × period / 2cond[2] = k0 × z_sourceStructure Typesnanocupstruncated conesnanopillarsnanodisksring-like resonatorsrelated plasmonic geometriesCombined_vectors.json and includes structure informarion in fabrication-aware encoding, more information in Github repo.GitHub repository: github.com/MrChen156/MetaField
