Abstract :
Reflection of TE0n modes (n = 1-6) at an oversized, open-ended circular waveguide was investigated theoretically employing scattering matrix codes, a FDTD code and UTD as well as the first time experimentally. The measurements utilized mode converters for generation of pure TE0n modes and a wavenumber spectrometer for directive mode analysis in the oversized waveguide. The computed total power reflection is 4.1 to 13.4 dB lower than calculated from free space wave and waveguide mode impedances, in agreement with experiments.
