Abstract

fetched live from OpenAlex

In this paper, we present the design and development of a wideband circularly-polarized (CP) conical horn antenna. The innovation lies in the incorporation of a linear-to-circular polarization (LP-to-CP) metasurface converter, strategically positioned at the aperture of a linearly polarized (LP) conical horn. Through simulations, our results showcase an impressive 3-dB axial ratio bandwidth spanning approximately 20%, alongside a peak gain of 18 dBi. Our proposed CP horn antenna features a compact dimension, a reduced weight, and an enhanced cost-effectiveness contrast to conventional CP horn antennas.

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.
