Performance evaluation of 3D FEM-based simulators in modelling scattering problems with metamaterials

This contribution is focused on the evaluation of the performances of three-dimensional finite element methods in solving electromagnetic scattering problems involving metamaterials. Finite element methods can be effectively used to provide a convergent approximation for investigating the unusual properties of metamaterials. However, an exhaustive assessment of the performances of the method, both in terms of its accuracy and of the required computational resources, has not been performed yet when metamaterials are involved. This paper addresses this topic by considering the 3D electromagnetic finite element modelling of the scattering properties of simple objects made up of metamaterials.
