Abstract (en)
[origin: US4636689A] This transformer (9) is formed by a waveguide, of approximately elliptical cross-section, and with increasing eccentricity (e) along the axis (z) of the transformer. This transformer (9) is connected on one side to the cavity (1) of a gyrotron (11) and on the other side to a section of guide (13) having the same cross-section as the final cross-section of the transformer and of which the cross-section is constant along the axis (z) of the transformer. The transformer receives from the gyrotron cavity a complex mode, of TEon type, and changes said mode into a mode in which the electrical field is approximately parallel to a given direction (z). A system of two mirrors (M3 and M4) enables a single beam of plane waves (19) to be obtained from the two beams of plane waves (14 and 15) obtained at the output of the section of waveguide (13).
