Abstract

fetched live from OpenAlex

The design and analysis of reflectarray antennas (RAs) often applies the local periodic assumption, whereby all elements are assumed to be identical. However, elements in a RA design differ geometrically from their neighbors, which can result in undesired perturbations of the reflectarray antenna pattern. In this paper, we explore the use of parasitically loaded elements in the reflectarray unit cell to compensate for this effect. An optimization scheme is integrated in the design process to improve the antenna pattern. As a proof of concept, the optimization of a plane-wave re-direction surface is 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.
