Abstract
Averaging the permittivity and permeability functions at the location of a material interface has become the most popular method to enforce the field continuity conditions in finite-difference discretizations of Maxwell's equations. While this approach offers unparalleled simplicity, the global error performs poorly—worse than first-order accuracy—when the sign of the material functions changes across an interface. In this paper, a new domain-decomposition method for enforcing the field continuity conditions is introduced that offers a second-order accurate global error performance even when the permittivity and permeability functions have a sign change.

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
