Abstract: This paper presented the elementary principle and the computation for waveguide eigenvalues by using mixed method (Quadric-FE-BEM). A general computer program based on the mixed method is programed, as an application, the cut–off wavelength of higher order modes in the rectangular waveguide are computed and the calculation results are well in agreement with the theoretical value. It has been shown that the mixed method is an effective method to analyze waveguide eigenvalues in engineering. At last, the cut-off wavelength of higher order modes in TEM Cell of homogeneous dielectric is also analyzed.
