Design and Demonstration of Shapeshifting Electromagnetic Reflector with Decoupled Phase and Magnitude Control.
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 reconfigurable reflector utilizes a stepper motor array to displace metasurface columns for 1D beam-forming at X-band frequencies, affording real-time de-embedding of phase to endow fully decoupled phase coverage. The reflector system consists of an array of panels of sub-wavelength split ring resonators loaded with PIN-diodes for reflected magnitude control. The real-time beam-forming feature of the proposed reflector system is experimentally demonstrated using of single beam steering with gain control, symmetrical dual beam-steering, and the asymmetric dual beam-steering. The last capability in particular is achieved through complete decoupling between the reflection magnitudes and phases. Finally, this work concludes with remarks on extensions of this concept towards alternative electromechanical reflector systems, where focus is given to their miniaturization towards mm-wave and sub-THz operation through the incorporation of tuneable graphene-based resistive elements.

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.
