Analysis of hollow elliptical waveguide with metamaterial cladding
Bibliographic record
Abstract
We characterize the behavior of modes propagating along a hollow elliptical waveguide with lossy metamaterial cladding. The proposed metamaterial-dielectric elliptical waveguide supports surface-plasmon polariton (SPP) and hybrid ordinary-SPP modes in the operating frequency ranges. Previous studies on metamaterial-dielectric elliptical waveguides either ignore the effect of energy loss on the modes characteristics or employ approximate approaches to characterize modes behavior. Although some previous works include energy loss, they do not specify SPPs propagation versus hybrid-ordinary SPPs propagation in the operating frequency ranges. Here, we consider energy loss in the waveguide to eliminate errors resulting from neglecting the loss. Our waveguide structure facilitates SPP and hybrid ordinary-SPP modes propagation along the waveguide, has better energy confinement, and higher propagation length than previous results in the literature. In the elliptical waveguide, the propagation coefficient changes by changing the waveguide eccentricity; therefore, the elliptical nature of the studied waveguide facilitates its applications in pressure optical sensors.

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.
