3D-Printed Conformal Meta-Lens with Multi-Mode Orbital Angular Momentum (OAM) Generation and Beam-Steering Capabilities
Bibliographic record
Abstract
This paper introduces a 3D transmitting cylindrical conformal meta-lens designed for height-to-phase-controlled electromagnetic beam control, specifically Orbital Angular Momentum (OAM) generation and beam-steering functionalities. Comprising 40 × 20 independently tunable unit cells using 3D printing, the meta-lens achieves full 360° phase compensation. CST Microwave Studio is employed for unit cell and full structure analysis, with a probe antenna illuminating the meta-lens. The proposed antenna achieves both OAM modes generation and beam-steering by evaluating necessary phase compensations for each meta-atom. Simulation results demonstrate two distinct OAM beam scanning techniques—single-beam and dual-beam steering—at different angles. This capability can be extended to enable wider 2D beam scanning, showcasing the meta-lens as a potential low-cost candidate for high-gain beam-steering mm-wave communication systems.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
