Abstract

fetched live from OpenAlex

This paper focuses on some features and developments pertaining to the source reconstruction method (SRM), an electromagnetic inverse source technique, for near-field antenna measurements. In particular, we describe the usefulness of the absence of restrictions on the measurement and reconstruction domains in the inverse source framework, which can lead to the development novel systems such as a pendulum-based measurement system. The application of the inverse source framework to phaseless (amplitude-only) near-field measurements using a multiplicative regularization scheme is reviewed, as well as the use of pre-scaled measurement data to improve the accuracy of the calculated far-field pattern.

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.
