Irregularities in a metal-dielectric shielded waveguide with low losses for the frequency range 90–100 GHz

This article is devoted to the study of waveguide metal-dielectric structures in frequency range 90100 GHz with low losses up 0,05 dB/m. The paper considers effect sharp irregularities on a section regular line, which leads change parameters closed path. In practice, have negative impact transfer characteristic waveguide. Therefore, types often found modern devices were investigated. As result analysis caused by rupture dielectric rod and rotation polarization plane, approximated characteristics function line irregularity obtained.
