Abstract : The design of the transition section used to excite the 'curved' model waveguide was completed. Although the design of the transition section is not directly related to the effects of perturbation in the curved model waveguide, it is necessary in order to facilitate the analysis of the scattering phenomena observed in the model. Two specific aspects of the design problem of the transition section was discussed that are strongly relevant to the problem of scattering in the model waveguide. The first is the WKB phase integral used in the evaluation of the scattering coefficients, and the second is the validity of the 'constant' finite surface impedance concept.
