| abstract | 805,510. Waveguides. MARIE, G. R. P. Oct. 22, 1956 [Dec. 31, 1955], No. 32174/56. Class 40 (8). A three-stage transition member for coupling a rectangular waveguide to a cylindrical waveguide comprises (a) a first stage (Fig. 2) the cross-section at each end of which is rectangular; the length of the longer sides 27, 28 and 29, 30 of one rectangle being substantially twice the length of the longer sides 21, 22 and 23, 24 of the other rectangle; (b) a second stage (Fig. 3) one end of which is connected to and is identical with the larger end of the first stage and the other end is of cruciform cross-section having four branches, e.g. 41, 42, 43, 44 of equal length and (c) a third stage (Fig. 5) having one end connected to and identical with the cruciform end of the second stage and the other end of circular cross-section. The outer ends of the branches 41, 42, 43, 44 are bounded by arcs of a circle of the same radius as, and concentric with, the circular end of the third stage. The transition member is adapted to convert a H 01 wave introduced thereinto from a rectangular guide connected to its input end to a H 01 wave for propagation in a cylindrical guide connected at its output end. The manner in which the electric field changes during passage of such wave through the member and geometrical details of the shape of the complete member (Fig. 1, not shown) are described. The said member may be made by depositing copper electrolytically on a suitably worked aluminium mandrel, and dissolving the aluminium. |
