Wide‐band polarisation‐independent metasurface‐based carpet cloak
Bibliographic record
Abstract
Although the ability of metasurfaces to control electromagnetic wavefronts has made it possible to design ultrathin carpet cloaks, the narrow operation bandwidth limits the performance of these cloaks. Here, the authors propose a new method to enhance operating bandwidth of metasurface‐based carpet cloaks. The proposed cloak consists of super‐cells providing appropriate phase shift to incident wave over a wide and continuous range of frequencies. Using the proposed method, a polarisation‐independent wide‐band single‐layer carpet cloak is designed and fabricated. The performance of the proposed technique is verified using both numerical and experimental data. Experimental results show that the cloak operates well at all frequencies in the range of 9–10 GHz. The proposed method can be used for designing single‐layer wide‐band metasurface‐based cloaks and illusion coatings at different frequency regimes.

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.
