A Wideband Dual-Polarized 1-bit Unit Cell for Reconfigurable Intelligent Surface Applications
Bibliographic record
Abstract
In this paper, a wideband 1-bit dual-polarized unit cell has been presented at Ku-band. It comprises three substrates and four metallic layers. The proposed structure uses polarization conversion technique, and out of phase characteristic of electric field in patch dominant mode to get two phase states. Using this characteristic provides the proposed structure with considerable bandwidth and accurate phase difference between two states. Two PIN diodes are used as switches for two phase states. Activating one diode for each state results in the conversion of x-polarized to y-polarized (and vice versa) incident wave with a 180°phase difference between the two states. Notably, only one control voltage suffices for both diodes, simplifying the design of the control system. The proposed structure has been simulated using CST software. Numerical results show good matching and 180°±2°phase difference between two states from 11.2 GHz -14.2 GHz with 25 % relative bandwidth. The proposed structure can be used for different beamforming, beam steering and RIS applications.

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.
