Abstract
Summary form only given, as follows. When solving Maxwell's equations using high-order finite-difference methods in the presence of dispersion, it is particularly important to have an appropriate procedure to model material interfaces that can handle nonuniform grids. This paper shows that, if such procedure is in place, then is possible to achieve high-order convergence using coarse discretizations even in the extreme case of analyzing a Lorentz material interfaced with vacuum and excited at its plasma frequency.

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
