Pagination or Media Count:
A Te sub 01 circular mode waveguide expansion joint, tapered transition device in which the expansion joint includes a linear tapered section, the greatest diameter of which does not exceed the cutoff diameter for the Te sub 01 spurious mode. A second taper of the cosine or other suitable type minimizes Te sub 02 mode generation as the guide diameter increases past the Te sub 02 cutoff value. The expansion, transition device simultaneously performs the functions of expansion section and waveguide diameter transition for the Te sub 01 circular mode while minimizing spurious mode generation.
