Although the main approach consist in solving the wave equation for the electric field, it was decided to use the approach of electromagnetic potentials V and A because those potentials give a simpler solution for both, the electric and magnetic fields. Besides, a comparison with theory was made, solving for an electromagnetic field without boundaries produced by an oscillating punctual source.enghttps://v2.sherpa.ac.uk/id/publication/issn/0277-786Xinfo:eu-repo/semantics/conferencePaperFinite elements methodScalar potentialVector potentialElectromagnetic wavesAbsorbent boundaries2021-03-26Marín-Suárez, M.10.1117/12.2229147
