Single frequency 2-D leaky-wave beam steering using an array of surface-wave launchers
Bibliographic record
Abstract
A planar antenna that utilizes surface-waves (SWs) for leaky-wave (LW) excitation is presented for millimeter-wave applications. Specifically, a two element array of directive Yagi-Uda like surface-wave launchers (SWLs) is used as the antenna feed, exciting cylindrical SWs on a grounded dielectric slab. By varying the relative phase difference between elements, the excited SW field distribution can be controlled. With the addition of metallic circular strip gratings, suitable conditions for LW excitation can be achieved. Essentially cylindrical LWs can be steered to confined regions on the guiding surface. For instance, by changing the relative phase difference between SWL sources such aperture fields can produce pencil and conical-sector beam patterns that can be steered in the far field at a single frequency. To the authors knowledge this is the first time such a LWA has been designed, fabricated and measured.

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.
