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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
