A Mechatronic Shape-shifting Reflector System with True Independent Reflection Magnitude and Phase Control for Dynamic Beamforming
Bibliographic record
Abstract
A novel shape-shifting mechatronic reflector system is proposed and demonstrated experimentally with a variety of real-time beam-forming examples. The reflector system consists of a 1D array of panels of sub-wavelength split ring resonators (SRR) loaded with PIN-diodes for reflection magnitude control, and a stepper motor array which de-embeds each panel to accomplish column-by-column phase control, thus offering excellent decoupling between the magnitudes and phases. A complete system prototype is built including a printed circuit board (PCB) based resonator array forming the reflector front end, a stepper motor array assembly, a custom built chassis using 3D printed parts and a fully programmable analog and digital electronic backend for PIN-diode biasing and motor control. The real-time beam-forming feature of the proposed reflector system is further experimentally demonstrated using the illustrative examples of single beam steering with gain control and generation of asymmetric dual beam radiation patterns where the two beams are independently controlled - a capability unlocked through achieving true decoupling between the reflection magnitudes and phases.

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.
