1. A method of operating a waveguide device, the method comprising:
receiving, by a main waveguide, a combined radiofrequency wave signal comprising first and second radiofrequency wave signals orthogonally-polarized from each other, the main waveguide having a blind end adjacent first and second auxiliary waveguides that are disposed perpendicular to the main waveguide and opposing each other;
splitting, at an orthomode junction disposed at the blind end, the combined radiofrequency wave signal into the first and second radiofrequency wave signals, the orthomode junction comprising a deflection insert having portions with opposing domed faces facing the first and second auxiliary waveguides, respectively, one of the domed faces being smaller than the other larger domed face, the deflection insert having flat faces facing a same auxiliary waveguide as the smaller domed face, and the flat faces extending from a first outer edge of the smaller domed face to a second outer edge of the larger domed face;
routing the first radiofrequency wave signal through the first auxiliary waveguide; and
routing the second radiofrequency wave signal through the second auxiliary waveguide.
