Abstract

fetched live from OpenAlex

In this article, we develop a novel algorithm for jointly optimizing the excitation voltages and the load impedances of arbitrary arrays of multiple active and multiple reactively loaded passive dipoles. The proposed algorithm hinges on obtaining a closed-form expression for the optimal excitation voltages of the active elements as a function of the load reactances. Noting that the array gain is a nonconvex function of these reactances, we develop an upper bound on the array gain and we use this bound and the excitation voltages that achieve it to guide the search for the optimal load reactances. Our numerical results show that the proposed technique tends to achieve the upper bound within a relatively small gap.

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.
