Dataset for "Discrete Reconfiguration in Continuous Fields: A Coherence-First Framework for Structural Stability and Snap Transitions"

This dataset contains calibrated Vector Network Analyzer (VNA) Touchstone .s1p exports (complex S11 reflection coefficient) and the accompanying Python scripts used to reproduce the analysis and figures in the associated manuscript, “Discrete Reconfiguration in Continuous Fields: A Coherence-First Framework for Structural Stability and Snap Transitions.”The measurements were acquired on a shorted waveguide/cavity configuration and are organized around a reproducible “snap”/hysteresis phenomenon observed under parameter sweeps. The package includes (i) an anchor exemplar sweep, (ii) an isothermal control demonstrating persistence of the hysteresis under negligible thermal drift, (iii) a drive-level control testing robustness versus RF power, and (iv) a geometry scan (multiple cavity lengths in small steps) mapping a deterministic stability basin in which the effect appears.The included scripts parse the .s1p files, perform notch alignment, compute forward–reverse mismatch metrics (including the “Mismatch Ledger”), and generate the corresponding figures (PDF/PNG) directly from the raw exports. The repository is intended as a replication pack: all figures and summary quantities can be regenerated without proprietary software beyond standard Python scientific libraries.
