Abstract

The modal composition and dispersion of a 80-mm-long 1 μm-thick silver iodide (AgI) coated metallic cylindrical waveguide is unveiled by terahertz (THz) near-field time-domain microscopy. We demonstrate that the coating is not thick enough to develop the low-loss HE₁₁ mode, but may allow a robust discrimination between the TE₀₁ mode and the rest of the modes. The methodology shown here based on near-field time-domain microscopy along with numerical electromagnetic modeling allows comprehensive waveguide mode characterization.
