Realizing Antenna Arrays with Huygens’ Metasurface Pairs Based on a Moment-Method-Like Design
Bibliographic record
Abstract
Huygens' metasurfaces have demonstrated great potential at manipulating electromagnetic fields at will. While omega-bianisotropy has allowed to design a single reflectionless metasurface for transformations that conserve local power, many applications, such as antenna beamforming, require control of both the amplitude and the phase of the transmitted fields. Pairs of reflectionless omega-bianisotropic metasurfaces have been proposed to break the condition of local power conservation. However, constraints on the minimum propagation length between the two metasurfaces, often lead to bulky designs. Here, an alternative method of designing a metasurface pair for arbitrary control of the amplitude and phase of the output fields is presented. The method relies on a power-based point matching process at the two metasurfaces and allows multiple reflections in the region between them. The usefulness of multiple reflections on the compactness of the metasurface pair is investigated through the design of a Chebyshev antenna array featuring a single feedpoint.

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.
