In International Journal of RF and Microwave Computer-Aided Engineering, 30(10)1096-4290https://hdl.handle.net/10016/35435Several electromagnetic problems for verification purposes in computational electromagnetics are introduced. Details about the formulation of a generalized eigenvalue problem for non-lossy and lossy materials are provided to obtain a fast and ready-to-use way of verification. Codes written using the symbolic toolbox from MATLAB are detailed to obtain an arbitrary accuracy for the proposed problems. Finally, numerical results in a finite element method code are presented together with the analytical values to show the accuracy of the code proposed.10eng© 2020 The Author.International Journal of RF and Microwave Computer-Aided Engineeringpublished by Wiley Periodicals, LLC.Atribución-NoComercial 3.0 EspañaBasis functionsFinite element methodTestbenchValidationVerificationresearch articleTelecomunicacioneshttps://doi.org/10.1002/mmce.22342open access11010INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING30AR/0000029450
