High efficiency Ka-Band single layer air vias Reflectarray: Design and analysis
Bibliographic record
Abstract
Design and analysis of a linearly polarized Ka-Band single layer Reflectarray (RA) based on the principle of dielectric perforation, are presented. The phase characteristics of a single layer unit cell is obtained by varying single air via diameter, located at the cell center. A 340 degrees reflected phase is realized. The resulted 29*29 air vias array design shows good performance in lowering Side Lobe Levels (SLL) and cross polarization while providing wider bandwidth and higher aperture efficiency. The proposed RA provides a 3-dB gain bandwidth of 17.3%, SLL of -23 dB, Half Power Beam width (HPBW) of 6.2 degrees, gain of 28.3 dBi (at 30 GHz), and a maximum aperture efficiency of 59 %. For comprehensive understanding, incident, total and scattered fields are analyzed in terms of amplitude and phase.

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.
