Abstract

fetched live from OpenAlex

A reflectarray metasurface unit cell consisting of two coupled resonators and three variable controls is proposed. The configuration consists of an outer split-ring resonator (SRR) responsible for resonance at the desired frequency and includes two variable elements; one capacitive and one resistive. A dipole-ring resonator (DRR) is inserted inside the SRR with a capacitive element, creating a resonance at a higher frequency than the SRR. Variation of the DRR resonance affects both the magnitude and the phase of the lower resonance of the SRR. For any given constraint on the available capacitive or resistive values, the coupled resonator configuration provides a significantly enhanced reflection magnitude and phase variations compared to a single isolated resonator. Control over magnitude and phase is used to demonstrate four cases of beamforming in the X-band at 9 GHz: side-lobe level (SLL) reduction, beam-steering, beam-steering with SLL reduction, and dual-beam generation.

Full frame distilled prediction

Teacher imitation

Not 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.
