Abstract
Abstract Hybrid-epsilon-near-zero (ENZ) metasurfaces, consisting of nanoantenna arrays on thin films of ENZ materials, feature a coupled resonance spectrum and have gathered significant interest for their nonlinear optical properties and their use in electro-optically tunable metasurfaces. While typically assumed to have a uniform permittivity, the ENZ film often features a graded permittivity distribution as a consequence of either material growth or capacitive tuning. Here we assess the impact of such a permittivity grading on the coupled resonance spectrum and show that the presence of grading alone results in a strong shift of the transmission minima of the coupled resonance, providing a new design parameter for hybrid-ENZ metasurfaces.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
