3D Metal-Only Phoenix Cell and its Application for Transmit-Reflect-Array
Bibliographic record
Abstract
This paper presents a 3D metal-only waveguide-based phoenix cell. The proposed cell uses open-ended waveguides, which allow a portion of the incident wave to pass through the phoenix cell. It thus has the ability to control both reflection and transmission phases. Its principle is analyzed in detail. Two metal-only transmit-reflect-array antennas are then designed. The proposed transmit-reflect-array antennas are able to produce both transmitted and reflected beams at 16GHz in the target directions simultaneously. One of the transmit-reflect-array antennas is fabricated using selective laser melting 3D printing technology. The measured results show that a good agreement between the simulated and measured radiation patterns is achieved. The side lobe and cross polarization levels at 16 GHz are -15.3 dB and -23.1 dB respectively. The measured gain of transmitted and reflected beams at 16GHz are 25.7 dBi and 24.1 dBi respectively. Both the simulation and measurement results fully demonstrate the capabilities of the proposed 3D metal-only phoenix cell.

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.
