Fabrication and testing of a microstrip phase shifter using micromachined reconfigurable ground plane
Bibliographic record
Abstract
A micromachined phase shifter is implemented along a microstrip transmission line using thin film membranes in the ground plane. Actuation of the membranes controls the spacing of the transmission line to the ground plane, varying line impedance and enabling signal phase shift. Thin film copper membranes on silicon substrates were constructed using micromachining techniques. An array of five 4.3 mm diameter membranes phase shifted a signal by 30.0/spl deg/ at 12.08 GHz. A single 10.4 mm membrane demonstrated a phase shift of 37.1/spl deg/ at 11.01 GHz and 55.5/spl deg/ at 14.25 GHz. Continuous positioning of the ground plane membranes is possible, enabling continuous phase shift control.

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.
