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 was observed as compared to full 3-D Finite Element Method. Examples of applications are shown addressing dielectric resonators and metallic-post filters.

Abstract
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 was observed as compared to full 3-D Finite Element Method. Examples of applications are shown addressing dielectric resonators and metallic-post filters.File in questo prodotto:
