A Double-Resonant Huygens' Metasurface Unit Cell for Applications in Dual-Band Transmitarray Antennas
Bibliographic record
Abstract
In this work, a double-resonant Huygens' element is presented. The proposed unit cell incorporates two types of interleaved Huygens' elements, together constructing a double-resonant electromagnetic (EM) response. Each Huygens' element consists of pairs of dislocated, identical dog-bone and comb-shaped dipoles, etched on both sides of a low-loss dielectric substrate and aligned with the polarization of the incoming wave. A dislocation technique is used for its capability to achieve co-location of electric and magnetic resonances, thereby enhancing the transmission performance. The two distinct Huygens' resonances enable transmission performance across an ultrawideband spectrum while also providing extensive transmission phase coverage. A key advantage of the proposed Huygens' unit cell is its ability to control the resonances independently with certain limits on geometrical variations, facilitating dual-band operation at <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{2 3 ~ G H z}$</tex> and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{3 8 ~ G H z}$</tex>. Simulation results demonstrate that the structure achieves high transmission efficiency (insertion losses less than 2 dB) and approximately 300° of phase coverage, while maintaining independent control of both passbands.

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.
