Resonant light transmission through a nanohole in a metal film
Bibliographic record
Abstract
The maximum wavelength at which light can propagate through a rectangular hole in a metal is dramatically increased due to the existence of surface-plasmon (SP) waves along the edges of the hole. For example, a 15-nm-wide hole in silver can have a cutoff wavelength more than double that of a perfect electric conductor. Furthermore, we show that there is a Fabry-Pe/spl acute/rot (FP) resonance for light transmission close to the cutoff wavelength, which gives a peak in the transmission. Impedance mismatch between the hole and free space provides the reflection required for the FP resonance. Due to the SPs in the hole, the reflection coefficient is typically larger in amplitude and has a smaller phase-shift than what has previously been observed in microwave systems. Our findings using analytic theory, finite-difference mode calculations, and finite-difference time-domain simulations agree well with recent experiments on the transmission through subwavelength rectangular holes. The transmission resonances found in a single subwavelength hole are of interest to nanolithography, biosensors, subwavelength microscopy, and photonic integrated circuits.

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.
