Abstract
Abstract A simple structure of an asymmetric cross shape metamaterial perfect absorber (MPA) on commercial Kapton film is designed and experimentally measured. The fabricated sample is thin, cheap, and ultra-flexible, which makes it possible to integrate onto curved surfaces. Two distinct absorption peaks are experimentally achieved with near-unity absorbance, which shows good quantitative agreement with the simulation result. A laconic multiple reflection interference model is established to describe the main features of the absorption spectrum. The dependencies of the geometry parameters, such as the asymmetric factor and spacer thickness, on the resonance frequencies and line shape of the absorptions are studied both analytically and numerically. By investigating the proposed structure as an index sensor, a bulk sensitivity of about 127.3 GHz per refractive index unit and a maximum value of the figure of merit (FOM * ) of 46.8 are achieved, which provides an alternative way for material recognition and dynamical index monitoring for liquid materials.

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
