T1 SUBMILLIMETRIC-WAVE RANGE REJECTION FILTER OF SPURIOUS HYBRID MODES IN HOLLOW DIELECTRIC WAVEGUIDE JF Telecommunications and Radio Engineering JO TRE YR 2012 FD 2012-04-19 VO 71 IS 2 SP 177 OP 185 K1 submillimeter-wave range K1 hollow dielectric waveguide K1 hybrid-mode suppression AB The breadboard modes of rejection in a circular hollow dielectric waveguide has been analyzed and experimentally studied. The filter is a waveguide segment bounded by two planar one-dimensional wire grating. This type of filter suppresses spurious modes down to 15...20 dB, as the operating HE11 mode gets damped down to 3 dB at 300 GHz in a waveguide of diameter 20 mm.
