Abstract
This paper proposes a 1-bit reconfigurable transmitarray system operating in the X-band that is capable of implementing a space-time coding scheme. The proposed transmitarray consists of a 10×10 array of unit cells, each exhibiting high transmission performance and offering precise 1-bit phase resolution. To enable the application of the space-time coding scheme, an FPGA-based control board is designed to ensure fast and accurate independent control of all unit cells. The proposed structure is designed using full-wave simulations and then fabricated for practical implementation, with measurements confirming the realization of active and harmonic beam steering through the implementation of the space-time coding scheme.

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
