OUT-OF-LIMIT WAVEGUIDE LOAD Russian patent published in 2013 - IPC H01P5/04 

FIELD: radio engineering, communication.

SUBSTANCE: out-of-limit waveguide load consists of a section of a rectangular waveguide with length of at least 2/5 of the wavelength at the highest frequency of the operating frequency band and a short-circuiting wall and is used in dielectric-filled waveguide channels. The out-of-limit waveguide load is used to reflect TE modes while maintaining phase and amplitude owing to the effect of coherent reflection of waves inside the section of the out-of-limit rectangular waveguide.

EFFECT: providing complete coherent wave reflection by a load in a wide band in dielectric-filled rectangular waveguide channels.
