Implication

Spectroscopic analysis demonstrates surface-plasmon resonance anomalies in metal gratings, suggesting higher-order plasmon-grating interactions form dispersion zone gaps.

Key Points

  • Analyze anomalous intensity variations observed in p-polarized light diffracted from concave gratings using surface-plasmon resonance principles.
  • Evaluated diffraction intensity anomalies for p-polarized light across concave diffraction gratings.
  • Constructed and analyzed surface-plasmon dispersion curves for aluminum (Al) and gold (Au) surfaces.
  • Identified distinct zone gaps within the constructed surface-plasmon dispersion curves of aluminum and gold.
  • Demonstrated that observed intensity anomalies correspond to second-order and higher-order plasmon-grating interactions.
