Abstract Higher order modes coupling characteristics in H11O, circular bending waveguide are analyzed according to the coupled wave equations, and coupling coeffecients of E01O, H21O, modes and their amplitudes are computed. A broad-band H21O, E01O mode filter has been presented. Experimental results indicated that its practical application is quite satis-factory. Thus, the problems presented by N. Nakajima, etc. can be solved.
