Triple Fano resonances in plasmonic heptamer nano-hole arrays: Symmetric and asymmetric structures
Bibliographic record
Abstract
The optical properties of gold heptamer-arranged nanoholes array have been studied numerically, for both symmetric and asymmetric structures. This array supports three Fano resonances arising from the excitation of localized surface plasmon polaritons (LSPPs), propagating surface plasmon polaritons (PSPPs), or/and waves related to Wood's anomaly (WA). To study the nature of each Fano resonance, electromagnetic near-field distributions have been computed, and the effects of the geometrical parameters has been carried out. In addition, the sensing performance of the structure has been examined, revealing that the highest bulk sensitivity (400 nm/RIU) and surface sensitivity (2 nm/nm) belong to LSPP Fano resonance, whereas, the highest figure of merit (24 RIU-1) is obtained by a coupled WA-PSPP Fano resonance, which is only supported by the asymmetric structure.

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.
