Near-field scanning probe terahertz microscopy is applied to identify the mode structure and composition in dielectric-lined hollow metallic waveguides. Spatial profiles, relative amplitudes, and group velocities of three main waveguide modes are experimentally measured and matched to the HE11, HE12, and TE11 modes. The combination of near-field microscopy with terahertz time-resolved spectroscopy opens the possibility of waveguide mode characterization in the terahertz band. date: 2009-04-27 official_url: http://dx.doi.org/10.1063/1.3126053 vfaculties: VENG oa_status: green language: eng primo: open primo_central: open_green doi: 10.1063/1.3126053 lyricists_name: Mitrofanov, O lyricists_name: Tan, T lyricists_id: OMITR95 lyricists_id: TMTTA03 full_text_status: public publication: Applied Physics Letters volume: 94 number: 17 pagerange: 171104-1 issn: 0003-6951 citation: Mitrofanov, O.; Tan, T.; Mark, P.R.; Bowden, B.; Harrington, J.A.; (2009) Waveguide mode imaging and dispersion analysis with terahertz near-field microscopy.
