Abstract :
A method for synthesis of TE01- TE11 waveguide mode converters is proposed based on the non-uniform rational B-spline technique. An application of the method to a 30.5-GHz serpentine circular waveguide converter of TE01- TE11 mode is given. The serpentine circular waveguide synthesized by the method has coaxial-parallel input and output ports and smooth axial curvature distribution, as well as short length and high conversion. The method offers good solutions to the problems of the mode converter design in the situation where two successive waveguides are asked to fit together strictly.
