| contents | A new approach for analyzing waveguide junctions containing conductive cylindrical objects is proposed. The algorithm is based on mode matching technique using local projection functions, which improves the numerical conditioning of the problem. Moreover, the approach enhances computational efficiency by reducing the boundary where the numerical integration is required. Both convergence and accuracy of the method were tested by using several examples, including multi-section microwave filters, and validated through comparison with results obtained using the finite element method implemented in a commercial full-wave simulator. |
