Abstract

fetched live from OpenAlex

A novel approach to evaluation of electrostatic multilayered media Green's functions is presented. Total field of the point charge in layered substrate is represented as a sum of known closed-form incident field in homogeneous space and scattered field which accounts for the effect of the layers. The former accurately approximates the field near the source while the latter is approximated with cylindrical waves and accurately represents the intermediate and far fields. The cylindrical waves approximation is performed via numerical solution of the differential equation formulated with respect to the scattered field as opposed to the total field as it was done in previous work. The spectral domain scattered field solution is cast into the pole-residue form. It allows for the subsequent analytical evaluation of the Sommerfeld integrals producing closed-form space domain approximation.

Not 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.
