This study explores surface plasmon propagation in metallic waveguides with alternating silver and gold stripes. The unique structure allows for tuning modal properties, offering control over plasmonic behavior in novel waveguide designs.

Area of Science:

  • Plasmonics and Nanophotonics
  • Materials Science

Background:

  • Surface plasmons are electromagnetic waves confined to the interface between a conductor and a dielectric.
  • Metallic waveguides offer unique properties for guiding and manipulating light at the nanoscale.

Purpose of the Study:

  • To investigate the propagation characteristics of surface plasmons in metallic multimode waveguides.
  • To leverage the differing properties of various metals (specifically Silver and Gold) in a striped waveguide configuration.
  • To analyze how structural parameters influence the modal spectrum and propagation behavior.

Main Methods:

  • Numerical simulations were employed to calculate propagating plasmonic modes.
  • Analysis focused on two distinct waveguide configurations.
  • Eigenmodes were visualized and analyzed for varying structural parameters like stripe widths and thicknesses.
