Millimeter-Wave Huygens’ Transmit Arrays Based on Coupled Metallic Resonators
Bibliographic record
Abstract
A novel Huygens' transmit array (TA) is proposed based on a coupled-resonator approach to demonstrate millimeter-wave (mm-Wave) beamforming for linear polarization. The proposed structure is simple and compatible with standard printed circuit board (PCB) processes and utilizes a single dielectric substrate only. It is shown that by engineering the geometrical dimensions of the resonator, its electric (even-mode) and magnetic (odd-mode) resonances are excited in a balanced manner to achieve zero backscattering in a large bandwidth. This operation principle of the proposed Huygens' cell is explained in detail using both an insightful equivalent circuit model, as well as full-wave eigenmode analysis. Next, the proposed Huygens' cell is placed on top of a high-gain 2-D slot-array antenna, in its near field, to engineer its aperture field distribution. Several TA prototypes designed around the 60 GHz frequency band are demonstrated and experimentally characterized in both their near and far fields, to achieve difference pattern generation, beam expansion, and beam steering as application examples, in addition to a uniform surface demonstrating its low-loss performance.

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.
