Reflectance analysis of a multilayer one-dimensional porous silicon structure: Theory and experiment
Bibliographic record
Abstract
We present a method for treating birefringent effects in layered media and apply the formalism to analyze reflectance from a multilayer one-dimensional (1D) porous silicon (PS) structure at off-normal incidence. The approach is to characterize the fields in terms of s- and p-polarized amplitudes in each layer, and the calculations then naturally employ Fresnel reflection and transmission coefficients for the uniaxially anisotropic media. We observe an excellent agreement between the theoretical and experimental curves by including optical absorption and macroscale waviness of the PS layers, and the resolution of the spectrophotometer. In particular, we point out the importance of birefringent effects that cause the splitting of the resonance wavelengths between two different polarizations. The investigated 1D PS structure can be used, for example, as a polarization sensitive optical switch.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
