A Dually-Polarized Leaky-Wave Antenna Based on Polarization-Selective Coupling Mechanisiam with Fixed Beams Capability
Bibliographic record
Abstract
In this work, we investigate the effect of polarization diversity for the higher-order space harmonics (HSH) of periodically-loaded leaky-wave antennas, i.e., TE10 and TE01. A hybrid form of nonradiative dielectric (NRD) waveguide and substrate integrated waveguide (SIW) is used to explore the inherent diversity feature for our antenna. The radiation properties of HSH in different passbands are examined where we investigate the behavior of scanning range variation of different HSH of n ∊ [-1, -2, -3, -4]. Furthermore, the effect of the unit-cell geometry on the propagation constant, and beam alignment of the TE10 and TE01 modes is studied and we show how the concept of HSH can be utilized for achieving a dually-polarized leaky-wave antenna (DP-LWA) with fixed beam operation. The proposed work is validated by showing an experimental prototype of DP-LWA in which a good agreement is achieved between the simulation, analysis, and measurement results.

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.
