Eccentric coaxial gap-plasmon aperture arrays for enhanced extraordinary optical transmission and applications
Bibliographic record
Abstract
The eccentric coaxial metal waveguide is similar to concentric coaxial structure, which has been studied extensively in the plasmonics community. Compared to the concentric structure, the eccentric structure has many benefits, including: (1)stronger subwavelength field localization around the narrowest gap, (2) improved optical coupling to the lowest order mode due to linear polarization, and (3) an increased effective index due to the gap plasmon. Yet, there have been no reports on the plasmonic aspects of this structure so far. This paper investigates on focussed-ion beam fabricated arrays of eccentric coaxial structures. An effective index method is used to analyze the field localization and enhancement. The gap plasmon is assumed dominant over conformal effects which can play an important role. Results show that the analytic theory agrees very well with a commercially-available finite-difference mode-solver(FDMS). Based on the simulations, strong modification to the extraordinary optical transmission peak is expected, with increased transmission over the concentric coaxial and cylindrical structures.

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.
