Abstract
A new sensitivity analysis method is proposed to compute the S-parameter Jacobian for metallic shapes. The method is exact in the sense that it uses an analytical formulation, which is independent of the method of numerical full-wave analysis and the respective system matrix. It uses only the field solution on the surface of the metallic objects. The field solution can be provided by any valid electromagnetic analysis. The computation is a post-process and its overhead is negligible in comparison with the simulation time. The method is validated with examples using a commercial finite-element-method simulator, which can provide not only the S-parameters but also their sensitivities. The method can potentially provide breakthrough capability for electromagnetic solvers, which currently lack sensitivity analysis, e.g., solvers based on the method of moments or the finite-difference time-domain method.

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
