An efficient algorithm is proposed to calculate the generalized scattering matrix in the case of a semi-infinite thin plate placed within the E-plane of a rectangular waveguide. It is based on the moment method for solving the integral Fredholm equation with respect to the electrical field distribution in the plane of the discontinuity. The second-kind Chebyshev polynomials are used as the basis and trial functions. Results of investigating the convergence of the developed algorithm are presented. It is shown that neglecting the plate thickness may result in a significant discrepancy between the expected and actual response functions of the bandpass filters constructed with the use of longitudinal strip diaphragms.
