Flexible and Portable Textile-Reflectarray Backed by Frequency Selective Surface
Bibliographic record
Abstract
A center fed C-band portable and rollable textilereflectarray (TRA) using frequency selective surface (FSS) is presented. The radiating elements are embroidered on the textile samples using conductive thread. The TRA is made of 15 × 15 elements (8.25 × 8.25λ2at 5.8 GHz) for broadside radiations. The embroidered flexible FSS aims to replace the solid ground plane. The element size variation backed by the FSS provides a 330° phase variation, which is adequate to design the TRA. Wideband multilayer stacked circular patches are utilized as a feed for the TRA. The antenna provides a measured 7.3% of 0.5 dB gain bandwidth, -15 dB sidelobe level, -25 dB cross polarization, and 29% maximum aperture efficiency.
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.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
