Abstract

fetched live from OpenAlex

A novel hexagonal Fresnel zone plate antenna is introduced and compared to the traditional circular Fresnel zone plate antenna. The comparison was carried out in simulation by using a finite-difference time-domain software. Although the circular lens performs better, the hexagonal geometry is better suited for arrays and provides the ability to both improve the sidelobe level and shift the sidelobe location away from boresight. This is accomplished by appropriately rotating the rings that make up the lens and is achieved without sacrificing directivity or 3dB beamwidth.

Full frame distilled prediction

Teacher imitation

Not 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.
