Error-controlled boundary element modeling of 3D plasmonic nano-structures via higher-order Locally Corrected Nystrom method
Bibliographic record
Abstract
Traditional low order numerical method of computational electromagnetics produce notably higher error when applied to analysis of plasmonic nano-structures compared to the structures with conventional values of permittivity and permeability. The high error levels are typically observed at the junctions of the low-order elements on the surface of such structures. It is caused by the artificial geometrical discontinuities resulted from flat panelled approximation of the physically smooth surface. Increase of the low-order discretization density typically does not reduce such error effectively. In this work we describe higher-order boundary element modelling approach which eliminates such errors and provides error-controlled approximation of the fields in arbitrary smooth 3D structures down to machine precision if necessary. The approach is based on higher-order Locally Corrected Nystrom discretization of the traditional surface Electric Field and Magnetic Field integral equations formulated for multi-region penetrable objects.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
