Abstract
This paper presents the design and experimental characterization of a planar 6 × 6 fully reconfigurable array operating at 5.7 GHz, capable of functioning both as a reconfigurable array lens and a reconfigurable reflectarray. First, the design of the array element, which consists of two varactor diode-loaded patches coupled by a varactor diode-loaded slot, is reviewed. Next, the design and fabrication of a planar array is described, and the varactor biasing scheme is discussed in detail. Experimental results demonstrating 2-D beamforming are presented, where a broadside directivity of 20.8 dBi and a beam-scanning range of 50° by 50° is achieved for the lens mode. The ability of the array to also function as a reflectarray is also demonstrated, achieving a directivity of 19.4 dBi at broadside and a beam-scanning range of 60° by 30°. Not only is this array able to demonstrate full 2-D beamforming, it is also low-cost and easy to fabricate, making it very attractive for applications where high-gain beam-scanning is needed.

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 it
