Zusammenfassung:The separation of variables method along with transformation theorem form Mathieu functions to Bessel functions are employed here to analyze the problem of a suspended strip in a circular waveguide. An infinite dimensional determinant is obtained which represents the characteristic equation of the proposed structure. To obtain the cutoff wavenumbers for both TE and TM cases of such a structure, the infinite determinant is truncated and convergence was observed. Numerical results for cases of interest are then presented.
