Abstract: | Theoretical and numerical results are presented on the propagation of infrared radiation in TE01-, TM01-, and TE11-like modes in an empty cylindrical, gold-coated waveguide of micron dimensions. Low-loss propagation is possible for the TE01-like mode, whose configuration is similar to that of the TE01 mode in a guide with perfectly conducting walls. Propagation is more lossy for the TM01- and TE11-like modes. While for small guide radii these modes resemble the TM01 and TE11 modes in a guide with perfectly conducting walls, they transform into surface waves as the guide radius is increased, with losses that are independent of guide radius |
