Abstract

fetched live from OpenAlex

In this paper, a symmetric double-layer wideband ultrathin Huygens' metasurface unit is presented. This unit cell is a good candidate for flat lens antenna for 5G applications. In this work, the bandwidth of the element is improved 34% which primarily affect the flat lens antenna bandwidth. This structure consists of a symmetric copper double layer unit including square ring and fractal patch structure etched on the one substrate. The proposed unit-cell excites both electric and magnetic dipole resonances with mutual interference. The simulated results show a high transmission (-2dB criteria) and 200° phase control at the same time, which cannot be realized by unit structures with double-layer. The whole thickness of the unit is also 0.046λ0 at mm-wave frequency of 28GHz.

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.
