A 2.5-D FEM Method for the Efficient Analysis of Waveguide Geometries With Cylindrical Insets
A new 2.5-D finite-element analysis method for waveguide geometries with cylindrical inclusion is presented. The method makes use of two 2-D meshes: one for the Cartesian geometry and one for the cylindrical geometry. The full 3-D solution is then obtained by combining several uncoupled 2.5-D problems which are solved separately. Excellent efficiency and accuracy were observed when compared to the full 3-D finite-element method (FEM). Examples of applications are shown addressing dielectric resonators and metallic-post filters.
