A Stacked Transparent Metasurface for Wideband LP-to-CP Conversion and Phase Control
Bibliographic record
Abstract
This paper presents a novel transparent metasurface that combines linear-to-circular polarization (LP-toCP) conversion with phase control. The metasurface consists of a Fabry-Perot metasurface for phase changes and an asymmetric chiral metasurface for LP-to-CP conversion. By stacking these two metasurfaces with an air gap and optimizing design parameters, the dual-layer metasurface provides both LP-to-CP conversion and phase compensation over a wide bandwidth. A proof-of-concept circularly polarized multi-beam antenna operating at 13GHz is designed, simulated, fabricated, and tested to demonstrate the effectiveness of the proposed metasurface. Results show that the antenna can generate five beams over a scanning range of ±10°, with a common 3-dB axial ratio bandwidth of 12.1-14.3 GHz and peak gain of more than 21dBi.

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.
