A new configuration of printed non-directive surface-wave sources for advanced beam control
Bibliographic record
Abstract
An array of surface-wave launcher (SWL) sources is presented for surface-wave (SW) control and beam steering on a grounded dielectric slab (GDS). Specifically, a four element array configuration of non-directive SWLs is investigated. By varying the relative phase difference and magnitude between SWL elements, the excited SW field distribution on the guiding surface can be steered and controlled. Simulations and measurements of a single SWL element are provided along with simulations of the proposed array. If metallic gratings or strips, or additional dielectric layers are placed on top of the GDS, the bound SWs can be transformed into radiated leaky-waves (LWs) and directive beam patterns can be generated in the far field. Examples are provided illustrating that broadside beam steering and circular polarization can be achieved at a single frequency. These slotted SWL arrays can be useful for novel SW beam scanning designs and other LW or cavity based antennas.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
