XIV Iberian Meeting on Computational Electromagnetics (EIEC 2022) Núria, Girona (Spain) 24-27 May, 2022

 

The XIV Iberian Meeting on Computational Electromagnetics was held in Núria (Girona) from 24 to 27 May 2022. EIEC meetings allow the exchange of knowledge between members of Portuguese and Spanish research groups working on computational electromagnetics applications in the various branches of Electrical Engineering by providing a highly specialized environment. These contacts contribute to forge closer ties in a community whose activity could be diluted in forums with a broader scope, favoring the establishment of partnerships that eventually lead to the development of joint projects.
