Abstract
A waveguide expansion joint for connecting two circular waveguides operating in the TE.sub.01 mode while allowing for waveguide expansion and contraction due to temperature variations. The expansion joint includes first and second rings on the outside surface at one end thereof. When the expansion joint is inserted into a waveguide the rings are proximate to the inside diameter of the waveguide for absorbing undesired propagating modes, for pressurization of the expansion joint, and for coaxially aligning the waveguide and the expansion joint.
