Abstract
A new topology for Huygens' metasurfaces (HMSs) is proposed as a means for dramatically simplifying the design of metasurface-based devices. Traditionally, the constituent unit cells for such metasurfaces are designed and optimized with many assumptions such as local periodicity, normal incident rectilinearly propagating excitation, etc. For applications demanding precise wave transformation, it is necessary to further optimize all the cells collectively to compensate for the inaccuracies of these assumptions. For complex designs with many degrees of freedom, this can be extremely time-consuming. In this paper, we propose a new unit cell topology, which intrinsically enforces the aforementioned assumptions, enabling rapid construction of metasurfaces from a library of preoptimized cells without the need for any subsequent tuning. To illustrate the effectiveness of the proposed topology, several devices are designed and verified numerically. For practical demonstration, a wide-angle reflectionless refracting metasurface employing the proposed unit cells is fabricated and experimentally tested.

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 it
