Modular-configured beam waveguide for transmitting microwave energy is formed of a plurality of cascaded modules each module containing a pair of reflecting surfaces, e.g. mirrors with the mirrors prealigned with one another and mounted in a supporting conduit or tube. Each tube or conduit module has a pair of orthogonal axes about which its joints with adjacent modules may rotate, so that with a plurality of such modules interconnected with one another, the overall configuration of serially connected modules may follow substantially any desired path. If desired, a module may be configured of a single L-shaped tube or cylinder at the bend of the L of which there is interiorly disposed an aligned mirror, either flat or curved, e.g. substantially elliptically configured for focussing purposes. The tubular construction may be conductive or nonconductive, its prime purpose being to provide support, rigidity and strength, as well as impermeability to external environmental conditions. Each open end of the tubular subsection of a module is of preferably circular cross-section with a rotationally mounted fitting for coupling to one of the legs of another L-shaped module subsection.
