Metamaterials are difficult to deal with in
computational electromagnetic modelling, e.g. finite element
analysis. The reason is the prohibitive discretization refinement
needed to account for their actual electromagnetic field
distribution profile, within the frequency range used in
contactless energy transfer devices. We propose an approach to
simplify the modeling of a metamaterial in finite element
simulations and present an analysis of its impact in the
evaluation of the magnetic field distribution in the vicinity of the
metamaterial.
