Abstract. The problem of radiation from the open end of an  non-uniform metal waveguide with curved walls generatriñes of which are arcs of circles is considered. Solutions are obtained for patterns of the Í10 mode in rectangular waveguide with curved walls in the E and H planes and H11, E01, H01 modes in a non-uniform circular waveguide. A hybrid method, combining the method of eigen functions, successive diffractions, and the principle of equivalence was used to solve the problem. The results of the radiation pattern calculating by the hybrid method, moment method, the finite element method, and the Huygens-Fresnel-Kirchhoff method are compared.

Key words: rectangular waveguide, circular waveguide, non-uniform waveguide, open end, hybrid method, radiation pattern.
