1. A waveguide assembly comprising(a) a waveguide having walls defining a cavity;
- said walls including oppositely located wall portions;
(b) a frame surrounding said walls of said waveguide;
said frame having a coefficient of thermal expansion less than a coefficient of thermal expansion of said waveguide; and
(c) first and second connecting spacers attached to and projecting away from said oppositely located wall portions;
said first and second connecting spacers being attached to said frame such that forces derived from a difference between a thermal expansion of said frame and a thermal expansion of said waveguide are transmitted by said first and second connecting spacers to said walls for deforming said walls.

Abstract
A waveguide assembly includes a waveguide having walls defining a cavity; and a frame surrounding the walls of the waveguide. The frame has a coefficient of thermal expansion less than that of the waveguide. First and second connecting spacers are attached to and project away from oppositely located wall portions of the waveguide and are attached to the frame such that forces derived from a difference between a heat expansion of the frame and a heat expansion of the waveguide are transmitted by the first and second connecting spacers to the waveguide walls for deforming the same.
