Abstract

fetched live from OpenAlex

We develop a high-order contrast source inversion method for solving the inverse scattering problem in electromagnetics. To decouple inversion from the mesh discretization, the algorithm supports high-order expansions for the fields, contrast and contrast sources on each element. The forward solver is a time-harmonic discontinuous Galerkin method formulated for Maxwell's curl equations and is sufficiently general to easily model a variety of imaging environments. Numerical and experimental results for transverse magnetic inversion are presented.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
