Researchers developed a novel waveguide for terahertz circuits using spoof surface plasmons. The L-shaped metallic element array offers deep-subwavelength confinement and long propagation length for terahertz waves.

Area of Science:

  • Physics
  • Electrical Engineering
  • Materials Science

Background:

  • Terahertz (THz) technology requires efficient waveguiding structures.
  • Existing THz waveguides face challenges with miniaturization and propagation loss.
  • Spoof surface plasmons offer a route to subwavelength confinement at lower frequencies.

Purpose of the Study:

  • To introduce a new waveguide design for terahertz circuitry.
  • To investigate the electromagnetic modes supported by the proposed structure.
  • To evaluate the confinement and propagation characteristics of the designed waveguide.

Main Methods:

  • Fabrication of a waveguide based on a 1D array of L-shaped metallic elements on a metal surface.
  • Theoretical analysis of the surface electromagnetic modes and their dispersion relation.
