Abstract:	We have extended the polynomial method to a unified approach to analyze hollow conducting waveguides of arbitrary cross section. It was found suitable only for lower order modes due to the singular matrix problem when the standard eigenvalue algorithm is used. In this paper, the QZ factorization for generalized eigenvalues is employed to overcome this drawback. The normalized cutoff wavelengths of the first 100 modes in the elliptic waveguides with different ellipticities are obtained using the present method and are compared with those of the analytic method. Excellent agreements are observed.
