Abstract
In this paper, the base station and the user communicate through double-RIS, while there is an eavesdropper on the user side, and the base station transmits confidentially through joint beamforming and phase optimization of the two RISs. This process considers the reflected communication channel between the two RISs. For the non-convex solution problem, we use an alternating optimization scheme for step-wise optimization. First, we can solve directly the closure expression for the beam assignment scheme. In contrast, the two-phase optimizations are complex fractional optimizations, which are then solved by converting the fractional form into an equation optimization with the assistance of transformations. Implementing the simulation surface, whether we deploy a single RIS on the user side or the base station side is inferior to the double-RIS 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
